The 41330 are available from vendors in the U.S.. Have you checked vendors in Europe? I can't find any info on the 23492 but if it has led's like the 41330 you might have to rewire it. You can avoid replacing the dc wheels by a current conducting adhesive but I think the shipping cost from the U.S. to Scotland would more than offset all of this if you can find someone who will ship for a reasonable price.

Hi David
Yes recent Trix and Märklin (and the Trix 23492 was offered in 2018) are identical to its Märklin equivalent. The only changes are the wheelsets and the box.
Märklin / Trix manages to play on standard current pick-ups either adapted to 2 rails or to 3 rails.
Chances are that except for presence detection, changing wheelsets is not mandatory.

PS I converted a Trix ref 22941 (241A65) loco (2 rails) into a 3 rails and only the current pickup is different (standard pratice by Märklin / Trix) and only the wiring was changed a little.

Cheers

I run Trix coaches and wagons in Märklin C and sometimes on K track without problems.
I don't change the wheels and they run ok, although I saw 1 video long ago where the Märklin wheels were shown to roll better on 3 rails C track turnouts.
Of course you have train detection in the rails, you need to change at least some (although I would change all or none).

Also long ago I had problems with Liliput wagon wheels on Märklin track. In some I changed the wheels and in others I pressed a bit the wheels in the same axle against each other and solved the problem.

Miguel
