Based on memory from the late 90s, stall 9 is the one that they use for the daily servicing, and passes through to the North. Both 8 and 9 have full length and width pits. Boiler washes usually happened in 8. 7 has the drop pit and connects with the machine shop. 5 and 6 have timber pits close to the doors. I dont think 4 had a pit.
Interesting they had the locomotive on the powered end of the table. That can get you into trouble if the tender is full. You can probably guess how I know that.
