- maximum axle load: 18 t (at a later, after adaptation of the infrastructure: 20 t);
- capable of pulling a wagon load of 430 t on a 26 ‰ gradient at a speed of 35 km/h;
- safe starting with this load on a 26 ‰ gradient and capable of reaching 35 km/h within 4 minutes;
- capable of two round trips Arth-Goldau - Chiasso (780 km) within 28 hours;
- electric recuperation braking system for decelerating the locomotive on a 26 ‰ gradient during 15 minutes without damage.
Apart from complying with the specifications, the Swiss Federal Railways (SBB CFF FFS) gave the design engineers great freedom to work out the designs.
