The Rhaetian Railway ABe 4/4 I is a class of metre gauge railcars of the Rhaetian Railway (RhB), which is the main railway network in the Canton of Graubünden, Switzerland.
The class is so named because it was the first class of railcars of the Swiss locomotive and railcar classification type ABe 4/4 to be acquired by the Rhaetian Railway. According to that classification system, ABe 4/4 denotes an electric railcar with first and second class compartments and a total of four axles, all of which are drive axles.
Created between 1946 and 1953 by the rebuilding of existing railcars originally built between 1908 and 1911, they carry the traffic numbers 30–38, and operate on the 1,000 V DC powered Bernina Railway. Since 1988–1990, when the ABe 4/4 III class railcars were placed into service, the ABe 4/4 I class has been much less frequently used on passenger trains. Following the deployment of the ABe 8/12 Allegra class railcars, only two ABe 4/4 Is are retained as heritage vehicles by the RhB, with one other preserved at the Blonay–Chamby Museum Railway.
