I designed these myself in CAD and printed them on my own 3D printer. The set includes a single story station building (27mm wide by 22mm deep by 16mm high), a chapel (10mm wide by 17mm deep by 20mm high), a signal box (12mm wide by 26mm deep by 22mm high), shed 1 (10mm wide by 8mm deep by 6mm high), shed 2 (8mm wide by 15mm deep by 10mm high).
