The game is also notoriously unstable with unusually high tendencies to hang, crash without giving reason, and display error messages incorrectly and/or at the wrong times. There are also issues with the signalling and AI dispatching. For example, the «front coupling bug», where the locomotive's front coupler would not work, the «white void bug», where the route scenery disappears, leaving a white void, and the «end-of-the-line bug», where the locomotive, if it crashes through the last buffers on the route, would fall into an empty void. The original version contained many bugs.
