This model and the Engine Shed kit (Ref 522) make a good starting point for any layout in need of steam engine facilities. An Inspection Pit (Peco LK-56/156) was also a common feature. Footprint: 140mm x 80mm.
The "Ratio 540 Locomotive Servicing Depot Coaling & Water Stage Plastic Kit OO Gauge" would be suitable for model railroaders seeking an authentic and detailed plastic-scale representation of a train maintenance facility.
