#br 641

The Baureihe 612 RegioSwinger is the fastest train on the route. It's a tilting Diesel multiple unit, and I already talked about it after my previous visit to Singen and Schaffhausen. It is the only type that runs the line in full between Basel Bad Bf and Singen as Regional Express (RE) 3, and does so in under 90 minutes (113 km @ 77 km/h).

Parallel to the express services are the omnibus Regional Bahn (RB), mainly RB 30 between Basel Bad Bf and Lauchringen. The workhorses on these routes are Baureihe 641 railcars, cousins of the French A TER, and Baureihe 644 Talent units. Coincidentally, both types were the final designs from small companies De Dietrich and Waggonfabrik Talbot in the 1990s, just before they were bought out by giants Alstom and Bombardier respectively (and later on, Alstom would absorb Bombardier).

Diesel multiple units need... well, Diesel, and if you were wondering, here's a fuel station, visible from the Swiss platform at Waldshut. Signs reading "612" and "644" on the right are clearly the stopping points for the types mentioned above. If you know how annoying it can be to have the petrol pump on the wrong side of your car, imagine how bad it'd be a for a train! Also, 641s can get lost apparently... (I'm guessing they can use another type's board.)

One track at Waldshut is electrified: the one to Switzerland, a country notorious for having electrified its entire passenger network. The train I boarded at Waldshut was a Thurbo-operated RABe 526 GTW, the one with the "power pack" module in the middle.
