I have just noticed the viaduct and am thinking it could have been used in either 'Here We Go Into The Wild Blue Yonder'
or 'Three Men And A Mangle'. I don't recall a viaduct in 'Full Steam Behind'
You're right stewpot. It's the Thornton viaduct from Three Men and a Mangle. The one from Here We Go Into the Blue Yonder is south of Horbury and west of Calder Grove.
Correct! This is where Truly, Clegg and Compo were in chase in Wesley's Landrover, and a few seconds later the Post Lady rides by with Foggy in the basket.
