South Alloa swing bridge in 2mm scale - an animated diorama

[Dunalastair]

Slightly larger than most of my dioramas, I have always had a soft spot for swing bridges, and the CR line into Alloa provides a good challenge for 3D printing - as did the munitions puffer (bound for RNAD Bandeath) and the Forth paddle steamer (with folding mast and telescoping funnel in case the bridge did not open in time). The period is shortly before closure, when railbuses provided a service from Larbert. The 1:148 railbus is string-powered, as the printed track is non-conducting.

 

 

And it does swing - as can be seen if if this video embeds correctly
