This is a large diesel engine service depot based on the one located in Tinsley, England.
Since this is not a symetrical structure, the dighole command only allows the inspection pits on the six
long tracks to be seen. The inspection track on the short pit can be made visible by carefully adding digholes.
I tested it with dig_hole_(1X1) - kuid2:210518:8578:1. A misplaced dighole is easily removed using the undo
button when initially placing the item on a route but can be quite difficult to remove later. Make certain
you have them properly located before exiting the session.
