Looking at the frog, you will see space where the wheels are not supported as they roll through. In real railroads, the angle of the frog is typically so slight that SOME portion of the wheel is always supported, or if not, the flange of the wheel will roll in the "flangeway" betwee...

Different railroads have different designs of whistle posts. Most modern ones are signs mounted on poles, but older styles include concrete pillars with a “W” molded into them. In both of these examples, the 1×1 tile is a stand-in for the 1×1 letter “W” tile (part no. 3070bpb0...

China and neighboring nations are quickly building standard gauge railroads. Standard gauge high-speed railroads have recently connected Moscow–Beijing and Beijing–Singapore. However, high-speed trains can only partly link neighboring nations with various track gauges. Technology, route dependence, ...

The installation of strain gauges on the rail required the welding of gauges to the rail using a portable strain-gauge welding unit. This process involved grinding the web and base of the rail to remove rust and expose pure metal, clamping a ground wire to the base of the rail, and ...
