37868 (Trix 22868) – SBB Class RBe 2/4 Electric Express Powered Rail Car As the "Rote Pfeile" / "Red Arrows" the Swiss Federal Railways (SBB) lightweight powered rail cars built in the Thirties quickly achieved a great deal of fame. Originally planned for service on routes with weak passenger loads, these popular powered rail cars soon drifted into excursion service. They were retired between 1966 and 1986 after different rebuilding programs and several new designations. Three "Rote Pfeile" / "Red Arrows" have remained preserved: RAe 2/4 1001 (SBB Historic), RBe 2/4 1003 (Transportation Museum in Lucerne), and RBe 2/4 1007 as an historic unit on the Oensingen-Balsthal Railroad (OeBB).
Prototype: Swiss Federal Railways (SBB) class RBe 2/4, "Roter Pfeil" / "Red Arrow", 2nd class, in the basic red paint scheme. Road number 607. The rail car looks as it did around 1957.
