Just a bit of information for those who run sessions. If a consist is sitting waiting for a specific time that you (or someone else) has included in the consists' instructions and you save and quit the game, when you re-open the session to continue the play, any consist that was waiting for a specific time may become stuck. It doesn't "see" the time instruction and won't move. This doesn't always happen, but I have seen it many times. I have to go to the locomotive and add a 5-second instruction to the driver. Then the driver will begin it's instructions again and (usually) will continue its run. Just FYI.
