You’ve got a great fleet there
@43055.
I especially like the mixed rake on the GWR HST with the odd purple coach clinging on.
I was looking at this though and feeling a slight sensation of fear and flashback...

Here’s a salutary tale for you:
When I had my 00 gauge layout in the loft in my old house I built it in a horseshoe right around the roof space.
Eventually I linked it up so it was one long oval and the link was over the loft hatch.
Now I fully intended on turning the link section into a kind of viaduct but for a little while it just stayed as an open stretch of board over the hatch (you can probably see where this is going).
One evening I was tinkering around with something while my (expensive and fairly new) Hornby 50007 ‘Sir Edward Elgar’ ran around the layout with a trailing load of eight Hornby Pullmans (yes the expensive ones with the lights in).
Unnoticed by me the rear three coaches uncoupled from the rest of the train and rolled to a stop over the loft hatch and sat there waiting for the inevitable, like some kind of terrible 1980s style rail disaster being played out in miniature...
Something out of the corner of my eye caught my attention and I turned just in time to see the 50 hit the back of the train with force, derail, fall off the layout and down through the loft hatch.
I think I caught the last two coaches after I’d thrown myself across the floor but it was an absolute horror show, and although I managed to glue the coaches back together they were missing all kinds of little details, and most were very badly damaged.
All that could be done with 50007 was to turn it into a dummy loco as all kinds of bits of the mechanism were damaged beyond repair.
Absolute nightmare.
So yeah, don’t leave the sides of boards where the track is close unprotected is what this long rambling post is meaning to say.
