| Something for Dave Larrabee: tracks (largely) without trains. We're looking down the platform of the Solothurn station of the Regional Transport Bern-Solothurn (RBS) narrow gauge railroad toward the RBS engine shed. The track in the immediate foreground is the mainline to Bern. On the far left, the gray girder rail behind the traffic cone is the interchange ramp to the standard gauged SBB tracks. It's difficult to see from this photo, but the girder rail gradually slopes down. Between the girder rails are narrow gauged rails. The standard gauged girder rails sit higher than the narrow gauged rails, but slowly slope to become lower than the narrow gauged rails. As the standard gauged cars travel across the higher girder rails, narrow gauged dollies are placed under each axle, so that as the standard gauged rails lower, the cars are suspended on the narrow gauged dollies. |
