Ae 4/4 – historic locomotive
The locomotives delivered between 1944 and 1954 were the first modern four-axle locomotives with bogies that were able to achieve an output of 1,000 hp per axle. In this sense, the Ae 4/4 locomotives were the precursors of all modern four-axle high-performance locomotives.

History historic rail vehicle
The locomotives delivered by SLM and BBC between 1944 and 1954 were the first modern four-axle locomotives with bogies that were able to achieve an output of 1,000 hp per axle. In this sense, the Ae 4/4 locomotives were the precursors of all modern four-axle high-performance locomotives.
The Ae 4/4 locomotives were modernised over the years as follows:
- Replacement of step switches
- Replacement of main oil circuit breakers with main air blast circuit breakers
- Replacement of driver's brake valves
- Doubling of the output of the electric brake. The removal of a pantograph doubled the braking resistances on the roof and thus braking power as well
- Replacement of leaf springs for the suspension system with rubber springs
- Replacement of ventilation louvers with jet nozzle grilles
- Adhesion improvements through the use of a control cable powered by electricity from the traction motor – this put additional weight on the leading axles
