The little yellow studs can be removed, i think they are glued but come out with a knife.
I would like to see a set with tanktainers, Bruhn, GCA Tainer, Eurotainer, Dana, etc.
Looking at the instructions for detailing parts i think you are showing the vac pipe going on upside down.
If it is put on the right way up the coupling may not hit it.
Looking forward to these.
The tracking number doesn't seem to work when you click on the link.
This was the same with the Rawie buffers, it did not work either.
Working from a real track plan gives this much more realism by placing track in positions that
you would not think of doing yourself, which is something i really like in a layout.
Looking forward to more progress.
Can you get at the switches for the lights from the top?
I love the cooling fan, it would be nice if it went round.
On the IRM website for the loco's spec it does say there will be two speakers.
