I tried this dual-track crossover piece. There are two problems with it, which seem to be serious bugs. First, the arrows which indicate the switch positions look always the same (this is the same problem with every other NAM rail piece that contains a switch). Therefore, it is impossible to tell which way the train will go. The second problem is that, although the train changes the track at the switch, but after leaving the crossover piece, on the next dual track tile it immediately jumps back to the original track, which looks ridiculous.
