2nd class InterCity compartment car type Bwmz of Deutsche Bahn AG. Model with air conditioning.

■ Prototypical implementation of all details

The demand for ICE replacement trains resulted in a shortage of second-class carriages in the DB long-distance division – while at the same time there was a surplus of first-class coaches. For this reason, some carriages in the inventory were downgraded for use in normal Intercity trains as "back-up carriages." Due to their high level of comfort, these carriages proved more popular with customers. These downgraded carriages are the perfect addition to existing trains and can even be used exclusively in faithfully replicated replacement trains.
