The Bernina-Bahngesellschaft Fe 2/2 51, later known as the Rhaetian Railway Fe 2/2 51, and reclassified in 1965 as De 4/4 151, is a metre gauge baggage railcar currently operated by the Rhaetian Railway (RhB), the main railway network in the Canton of Graubünden, Switzerland.
The railcar has been so named under the Swiss locomotive and railcar classification system. According to that system, Fe 2/2 (to 1961) and De 2/2 (since 1962) denote a vehicle with a luggage compartment and a total of two axles, both of them drive axles.
In 1943, the railcar entered service with the Rhaetian Railway, upon that railway’s takeover of the BB. The railcar has continued to operate on the Bernina Railway ever since the takeover.
Over time, the Rhaetian Railway altered a number of the railcar’s specifications:
- 1951: the bow collector was replaced by a double-arm pantograph;
- 1961–62: the railcar was fitted with a new body, new controller box, and a compressed air shunting brake and track brake in addition to the existing vacuum brake;
- 1980: the body was clad in metal, and the pantograph was replaced by a single-arm unit.
While in service with the BB, the railcar was painted grey. After the Rhaetian Railway takeover, it was initially liveried in green and later relivered in brown. Since the early 1990s, it has carried a traffic orange livery.
