First Machine Shop car has a stand grinder, a power hacksaw and a drill press with a pretty big table. Second has what might be a press, a lathe and a smaller drill press. I'd guess some of the work was repairing field artillery. Damage might be from heavy use, or from enemy action. The rest probably included fixing light railway equipment.
I have a bunch of projects planned and started. I am feeling deadline pressure so I need to fully focus on the WW1 layout for 9 months. Watch for a lot of activity.
