both the US and euro versons were catalog items for several years-from memory only-1988-2000 at least
value??? well provided they are in excellent condition- they have 2 buildings as i recall has station and freight house-lamps and trees and 3 switches, bumpers and other detail items-like figures and fencing and trees
but they are compact on the upside and limited operation on the down-
my guesstimate is about 500 or so- retail value of components would be higher _IF NEW- but they are fixed to the display so less and would be expensive to pack and to ship safely-obviously condition is key
