Hi Kevin,
You can do what you want to do in the game.
Just takes a bit of setting up beforehamd.
In surveyor, click on the the second icon to the right of the MENU Button.
In this window select ADD and choose the following rules. QUICK DRIVE and CLEAN UP DERAILED TRAINS or DERAILED VEHICLE REMOVER.
When you have created your consist open the train tab and select the TRAINS ICON. Using the GET CONSIST BUTTON, click on your consist and save it under any name you want.
When you have a derailment of this consist, wait for the derailment to be removed, then click on the USER RULES button in the top right of the screen (second icon from the left) and choose QUICK DRIVE.
In the window select NEW TRAIN and find your consist in the list. click on it and a small window comes up giving you the choice of PLACING CONSIST, REVERSE CONSIST, PLACE CONSIST AGAIN.
Make sure there is enough room to place the consist on the track.
If you need to you can add a driver in QUICK DRIVE or you can have the original drive MOVE TO TRAIN.
The beauty of doing all this is that you can create your favourite consists and add them at any time to any session anywhere.
Hope this helps,
Cheers,
Mike
