That layout has a nice flow. I didn't do cut-ins. The purpose was exactly what you did. I also didn't round out the benchwork.
I assume the track is on the rear of the furnace and it's serviced from the front.(side opposite the track).
I'll mod the first file.
Moonman -
Thanks! I really like the flow as well. I see opportunities here for an internal yard in the lower loop with an engine facility - down the line, it would also be easy to add on a yard down the North wall of the storage room.
Technical stuff:
Yes, furnace and water heater are both serviced from the East side of drawing. I'm thinking I will install a stud wall behind them to provide a backing between them and the layout - so layout would need to be completely accessed from inside in the furnace space under the stairs.
Looking at the drawing again, the stairs are under-sized to the east - they extend towards the furnace another foot or so - I drew them at 3 1/2 ft wide and I think it's closer to 4 1/2 - 5'. I measured furnace last night and it was exactly 17' to the back from the 18' west wall. I looked at the stairs and if I were to run a stud wall along them, it would line up perfectly to slip behind the back side of the furnace.
