RhB B 2304

In 1939/40, the RhB put the four railcars BCe 4/4 501-504 light railcar compositions into service with the AB4ü 251-252 and C4ü 2301-2306. The wagons with the characteristic front windows and central entrances, later called A 1251-1252 or B 2301-2306, were modernized in the mid-1960s and given new bogies. Its main area of application was the Arosabahn; today you can also see them on other lines as additional cars in peak traffic. With the exception of the A 1252, all vehicles are still in the Graubünden meter gauge railway fleet.
