I have the old Western Locomotive, but all my rails are the RC variety. It'll just look pretty somewhere...
The old rails looked a lot better... but I never got any trains back then. My first was the RC oldtimer.. then I got the 1st XMas trains and the Express, both RC on ebay. Right after I got the express, playmobil did a gorgeous yellow one. Bah.
I also hunted down a few western wagons, plus the grafitti wagon and a pretty cow spotted one from a weird brand.
Of course, I have no idea where I'll EVER find the space to put it all together
I remember the RC ones were big hits with my cat, back in the day.
