Giving road carriers the possibility of having their vehicles
transported by rail, this was the challenge that the French
engineer and industrialist Rene Porte, victim of an accident caused
by a crazy truck in the 1930s, set for himself. The idea is not new
since it had already been tested across the Atlantic, notably in
1926 by the Chicago North Shore and Milwaukee Railroad, but limited
to its simplest expression.
Filed on December 2nd, 1932, his patent application on
"Improvements in means of enabling the transport of rolling loads,
in particular vehicles, by railroad cars" is officially registered
on March 14th, 1933.

In 1934, the Company for the Union of Rail and Road Transport
(Société pour l’Union des Transports
Ferroviaires et Routiers -
UFR) is established with the support of:
- the French Railway Equipment Company (Compagnie
Française de Materiel de
Chemins de Fer -
CFMCF);
- the Automobile and Commercial Transport Company
(Societe des Transports
Automobiles et commerciaux -
STA);
- the Automobile Transport Industrial Company
(Societe Industrielle de
Transport Automobile -
SITA);
- the Neuflize bank.
President and CEO of the UFR, Rene Porte is working to make his
process operational. To do this, his company orders from the
private industry 75 wooden road trailers of his design (with a
payload of 3.6 t and 6 t) which it leases to carriers. These are
road semi-trailers adapted for the rail gauge (reduced height) and
are not intended for long haul journeys on the road, they are
designed for short distance terminal services. They are fitted with
auxiliary rims and a self-folding, balanced drawbar.

For their transport by rail, he obtains from the railways of the
Eastern Railway Company - Est
and the State Railways Administration -
Ouest-État the "precarious" transfer, for a
rent, of 40x bogie wagons which it ensures the transformation into
carrier wagons (25x units) and loader wagons* (15x units). 18.5 m
over the buffers, the carrier wagons (of the RRlyw type) can
accommodate five small trailers (3.4 m long) or three large
trailers (5.85 m long). In 1935, the UFR had 5 loader wagons built
at its own expense which, placed at the end of the quay, provided
an alternative to side loading and unloading. In 1938, it will also
draw up the plans for a mobile footbridge allowing to operate
directly from the road.
The flat cars are fitted with guide rails in order to center the
trailer in the rail gauge. The guide rails support the trailer
during rail transport thanks to auxiliary rims.
*With the development of the UFR system and the increase in
trailers weight, the use of a loader wagon and side dock will later
be limited to single-axle trailers with a total weight not
exceeding 11 t. As a result, the most suitable installation for UFR
trailers is an end quay fitted with centring guides or
equivalent.

The service is inaugurated on May 1st, 1935. UFR coordinates the
routing of freight cars in agreement with the main French railway
companies at the time, with the following routes available at the
beginning:
- Paris - Bordeaux route managed by the Railways from Paris to Orleans and the Midi -
PO-Midi;
- Paris - Lille route managed by the Northern Railway Company - Nord;
- Paris - Lyon route managed by the Railway company from Paris to Lyon and to the
Mediterranean - PLM;
- Paris - Strasbourg managed by the Eastern Railway Company - Est and the Alsace and Lorraine railways administration -
AL.
The initial schedule is at the rate of a departure every two days
soon followed by a daily departure two weeks later. The trip takes
24 hours, for example:
- departure from Paris-Bercy at 23:29 (day 1), arrival at
Lyon-Guillotière at 23:49 (day 2);
- departure from Lyon-Guillotière at 4:55 (day 1), arrival at
Paris-Bercy at 6:15 (day 2).
The traffic is still limited for each shipment to a wagon loaded
with three trailers. The pricing applied by the networks is
inspired by the "wagon-kilometre rate" which came into effect in
March 1933: the rental and transport of the wagon are invoiced
between 2 francs and 4 francs per kilometre, whatever the nature
and weight of the load.
Considering that the road transporters work during the day, the
trailers are taken in the morning at the station by tractors for
the distribution of their content. They are then brought back to
the station in the evening after collecting the new load. For
loading and unloading at the station, in addition to the
constraints related to the FAR coupling, the road tractor used must
have a width limited to 2.20m and have its rims fitted with discs
intended for centering between the guide rails of the wagons.

Other
trailer prototypes will subsequently attempt to compete with the
UFR system.
But only the one developed by the Company for Studies and
Mechanical Achievements (Societe
d'Etudes et de REalisations
Mécaniques - SEREM) will really
hold the attention: a trailer whose body, after retraction of the
rear wheelset, comes to rest directly on the floor of the wagon,
thus resolving the wedging problem while increasing the trailer
height.
SEREM, which filed its patent on November 17th, 1937, joined forces
with the CODER establishments of Marseille-Saint-Marcel for the
construction of the SEREM -
CODER trailers and freight wagons.

As a stakeholder in the development of measures governing rail-road
coordination, the SNCF has, from its creation, seriously considered
“door-to-door” techniques likely to hinder the development of road
transport. On November 8th, 1938, the entire SNCF managing staff
thus went to Paris-Batignolles station, invited by its Commercial
Department to a presentation of "home-to-home transport systems":
safety devices. handling, rail-road equipment (including, of
course, the UFR system).
In 1939, "in order to obtain a deflation of long-distance road
transport", the SNCF reflected on the means of organizing mixed
transport services by rail and by road. The use of UFR trailers is
retained as the most suitable means for this purpose. But it is
unthinkable to let UFR master the market. SNCF's position is clear:
it will itself provide the trailers and wagons suitable for road
companies who request them.
Approached, Rene Porte, ready to collaborate, transmits his
conditions on August 10th, 1939. He agrees to return to the SNCF,
as is, the 40x wagons given for hire and the 5x loading wagons
built by the UFR for 1.030.000 francs. This sum, which represents
barely two-thirds of the costs incurred by the UFR since 1935 for
the fitting out and the construction of these materials, breaks
down as follows:
- 640.000 francs for compensation for the 15x loading wagons (at a
unit price of 36 000 francs) and 5 loader wagons (at a unit price
of 20,000 francs);
- 150.000 francs for compensation for the 25x carrier wagons (at a
unit price of 6,000 francs);
- 240,000 francs for carrier wagons that SNCF deems fit to equip in
the future (at a unit price of 6.000 francs per wagon of three
trailers, 4.000 francs per wagon of two trailers and 2.000 francs
per wagon of three trailers).
Once the amount of 1.030.000 francs is paid, SNCF would be entirely
free to fit out new wagons and operate them as it saw fit without
having to pay any other fees to UFR.
SNCF accepts Rene Porte's proposal. But if the agreement settled
the fate of the wagons, the 75 road trailers remained the property
of the UFR. This time setting aside any idea of repurchase, SNCF
decided to acquire on its own funds 300 trailers with the aim of
reselling them on credit to interested road companies in order to
obtain better financial conditions from manufacturers by grouping
orders. To this end, the Board of Directors approved, in its
meeting of December 4th, 1940, the opening of two credits, one of
30 million francs for the construction of 300 UFR type trailers,
the other of 6 million to equip additional wagons.

The French National Railway Company - SNCF entrusts
the Professional Organisation Committee for the Industry and Trade
in Rail Transport Equipment with the task of finding the
manufacturers for the new material.
In the case of the UFR system, the best proposal comes from the UFR
company and a contract is signed on July 9th, 1941, for 170x metal
trailers with a fixed roof, 36x metal trailers with an opening roof
(both with a payload of 6 t) and 44x tanks for wine transport (with
a capacity of 6.200 l).
Not having its own workshops, the UFR divides the construction of
its trailers between four builders:
- the General Company for Construction and Maintenance of Railroad
Material in Villefranche-sur-Saone for 100 fixed-roof vans;
- the Lagache and Glatzmann Establishments in Argenteuil for 106
van chassis and 44 tank chassis;
- the Million-Guiet Establishments in Levallois-Perret for 70x
fixed-roof vans bodies and 70x open-roof vans bodies;
- the Digard d'Aubervilliers Establishments and Pinchard-Denis de
Noisy-le-Sec Establishments for 44x tanks.
The trailers ordered are primarily intended for road carriers who
have agreed to abandon part of their long-distance services in
favour of rail transport. During the war, thirteen companies signed
agreements to this effect: in exchange for handing over a quota of
goods to rail transport, they are guaranteed to receive a certain
number of these new trailers (either the UFR system or the SEREM -
CODER system to choose from) in full ownership (the financing
is covered for about 30% by the road companies and for 70% by the
French National Railway Company - SNCF) and the
insurance of having the platforms and wagons necessary for their
loading / unloading and their transport. Amendments are
subsequently made to take into account possible obstacles to
movement by rail and destruction of equipment attributable to acts
of war.
The first to sign is the Northern Automobile Transport Company
(Société des Transports
Automobiles du Nord -
STAN), based in Pierrefitte (Seine), owner of 27
trucks and 10 road trailers representing a tonnage of 290 t and
transport licences giving it the right to provide on-demand
services throughout France, a status which it is ready to renounce
against the promise of receiving 60x UFR trailers. Concluded in
early 1941, the agreement is ratified by the Secretary of State for
Communications on June 20th: by handing over 40x UFR trailers
(75.7% funded by the French National Railway Company - SNCF), STAN
undertakes to hand over to the French National Railway Company - SNCF at least
144,5 t of goods per trailer and per semester to be transported
from Paris to Lille, Nancy, Rouen, Le Havre, Ponts-et-Marais (Lower
Seine) and vice versa. In the event of non-compliance with the
contract, SNCF is entitled to take back the trailers.
Among the other signatory companies, we can cite the Bourgey &
Montreuil de Charnbery Company (agreement approved on September
22nd, 1941) which, with 13 open-top vans and 17 one-compartment
tanks, has undertaken to provide a minimum traffic of 160 t (per
semester and per trailer) between Chambery, Lyon, Marseille and
Paris and between Chambery and the wine centers of the South of
France.

Due to lack of wagon availability, the French National Railway Company - SNCF is
forced to use old two-axle Rzl freight cars. Of dilapidated and not
very robust construction, these wagons can carry only one trailer,
only at low speed and without being able to go through gravity
yards.
The State Secretariat for Communications gives its approval on
December 30th, 1942, for the acquisition of 15x new loader wagons.
Sources: Les rails de l'histoire n° 4 - https://issuu.com/gayalanouvelleagence/docs/journal_4_site/10
The shortage of materials delayed the execution of contracts and
deliveries of the new trailers are phased between 1943 and
1946.
As of December 31st, 1945, only 163x UFR-type trailers are in
service.
But the French National Railway Company - SNCF
anticipates an increase in demand after the war and even if the
1941 order is not completely delivered they do not hesitate to
order 350x additional road trailers in the summer of 1945 and 200x
carrier wagons in the winter if 1945. With two axles, 12 m long and
able to accommodate two trailers of 10 t each, these wagons are
intended to be included in the composition of fast trains and able
to pass through gravity yards.
Confirmed in 1946, the new order is split between the UFR system
(320x trailers, 175x wagons) and the CEREM-CODER system (30x trailers and 25x wagons).
The UFR materials will actually be delivered:
- between 1947 and 1949 for the trailers;
- in 1948 for the wagons.

From October 1st, 1945, thanks to the entry into service of a new
postal train service, a first contingent of UFR trailers was the
subject of accelerated routing tests on certain connections (Paris-
Lyon, Paris-Marseille, Paris-Bordeaux, Paris-Lille, in particular),
even before the official application, on January 1st, 1946, of the
accelerated regime for this category of equipment. But it was not
until the delivery, in 1948, of the wagons ordered two years
earlier, that all the trailers could fully benefit from this
measure.

Slowed down by the circumstances (some of the road companies didn't
receive any trailers during the war), road-rail traffic by trailers
experienced a sharp recovery in the aftermath of the Liberation,
going from 16.400 t in 1945 to 39.300 t in 1946, the largest
contingents being represented by wines and spirits (6.039 t), paper
and cardboard (1.810 t), glassware (1.422 t), mineral water,
furniture, accumulators, rubber.
At this date, only seven stations had specific loading-unloading
sites: Paris-La Villette, Nancy, Chaumont, Paris-La Chapelle,
Lille-Saint-Sauveur, Paris-Batignolles and Le Havre.
The same year, as the new carrier wagons ordered in 1945 are not
yet delivered (they will be delivered in 1948) and in order to deal
with the pressing needs, the French National Railway Company - SNCF proceeds
to the transformation of 200x flat units from its own fleet:
- 100x single carriers wagons registered 430000, 429501 - 429557 &
429958 - 429999 transformed from previous OCEM 29 freight wagons
delivered to the Railway company from Paris to Lyon and to the
Mediterranean - PLM and the Southern Railway Company - Midi between 1931
and 1934;
- 100x double carriers wagons registered 425801 - 425900
transformed from previous RRuw freight wagons delivered to the
Eastern Railway Company - Est and NNuw freight
wagons delivered to the Alsace and Lorraine railways administration -
AL in 1931.

As their number is limited, road-rail trailers must have a quick
turnaround according to a schedule established in advance. In
addition, each sending or receiving station must have road tractors
to provide terminal trucking. Indeed, in the absence of their own
tractors, the companies turn to independent tractor-owners, some of
whom are specialised in this service, such as, in Paris, the Paris
Auxiliary Company for Mixed Rail-Road Transport. As such an
organisation goes beyond the normal framework of its services, SNCF
encourages the creation of adequate structures like the creation of
the Technical Grouping of Mixed rail-road carriers
(Groupement Technique des
Transporteurs Mixtes rail-route
- GTTM).
This association governed by the 1901 law brings together around
their founding president Rene Mazeaud (1911-1986) consolidators,
commission agents and road carriers. Its local branches play a role
both commercially (relationship with customers) and technically
(reception of trailers and wagons, monitoring and maintenance).

From August 1st, 1948, all carrier wagons (362x intended for the
transport of UFR trailers and 50x for that of SEREM - CODER
trailers), loader wagons (13x), loader wagonets (20x) and
semi-fixed devices (38x) is transferred to the south-east fleet,
their maintenance being ensured by the workshops of
Villeneuve-Saint-Georges (UFR) and Marseille-Prado (CODER).

On October 5th, 1948, the French National Railway Company - SNCF
inaugurates in Ivry-sur-Seine the rail-road station of
Champ-Dauphin where all the departures and arrivals of trailers to
or from the Mediterranean, South-East and South-West regions are
now concentrated.
This ceremony shortly precedes the major “door to door” exhibition
held at the Paris-Batignolles station from October 11th to 16th.

In 1949, the French Company for the development of Mixed rail-road
transport (SOciété FRAnçaise pour
le développement du transport MIXTE -
SOFRAMIXTE), a public limited company whose
capital is held in large majority by more than a hundred
transporters, is created to manage the fleet of UFR wagons
(monitoring, maintenance, distribution) leased from the French National Railway Company - SNCF.
NB: Subsequently, SOFRAMIXTE will also manage the UFR wagon
fleet set up by SCETA. As it is also responsible for financing the
purchase of new equipment, it will be led to own its own UFR
wagons.

As of December 31st, 1949, 653x trailers and 382x carrier wagons
are in operation. 41x stations are equipped with loading and
unloading sites*. The tonnage transported amounts to 158.000 t
(compared with 59.500 t in 1947 and 91.000 t in 1948). In 90% of
cases, the duration of transport by rail is equivalent, if not less
than that of the road truck. In addition, an almost perfect
regularity is obtained since the planned routings are respected in
97% of cases.
*At its peak in the 1960s, there are around 185 stations in
France capable of handling UFR trailers. The system also covers the
metric gauge (CFD Vivarais) as well as some key points of the
German, Belgian, Dutch or Italian networks. The tonnage transported
amounts to 890.000 t per year carried by over 2.500 semi-trailers
(owned by 165 private companies) and 1,300 wagons (270
single-carrier and 1030 twin-carrier).

Although served by a maximum load of 17 t, far below that of
wide-body road vehicles which can reach 24 t, the UFR technique
experienced continuous growth until 1968, when the number of
trailers in circulation begins to erode (2.640 in 1968, 2.490 in
1969). This decline is explained in particular by the rise in
power, since 1959, of the Kangaroo technique which, using wagons
equipped with a pocket in which the wheels of the semi-trailer are
housed, are able to accommodate larger trailers. It accelerated
with the decision taken in 1971 by NOVATRANS to abandon handling by
specialized tractor in favor of vertical handling. The last UFR
trailer in operation disappeared in 1983.
