A Trio of Troublesome Trucks

When our children were small they enjoyed the stories of Thomas the Tank Engine - occasionally featuring the troublesome trucks.  

These are three of Gill's father's model trucks from his garden railway ... which was not at all troublesome!  The railway was in 16mm scale, so 16mm on the model would have been 1 ft in full size. The trucks are built up from kits, but he built the engines from plans cutting many of the parts from steel & brass stock on a lathe.

The best idea I could come up with for Mono Monday on the theme of trio.   Backblipped as I did something unfortunate to my lower back yesterday and was not in the mood for sitting at a PC later on - all ok(ish) now.
