Well with all this talk of new/old/secondhand/local or overseas, I have added the parts for the tunnel mouths, which will be a project for 2026, as well as a couple of containers, Swmbo insisted that I bought them as well, so who am I to argue.

I came accross the 3D printed prototype at a recent Model Railway Exhibition, and after one of those work it out on the back of a fag packet type excercises, emailed back and forth to the supplier,

...from my prospective with teathered pantographs (with fishing line as seen in the middle of the pantograph.) in order to fit through the LGB girder bridge, I should get away with just the prototype, without using the extension pieces. I may also have made a basic adding error in my height calculation for the extension pieces, but I am sure they can be trimmed if need. Not sure if I will paint them or not, but as I have said it's something for next year.
