Excellent condition with nice original paint and the "Tunnel" decals - there are a few small paint chips and marks, but overall for it's age the paint is excellent. Decals are all present and nearly complete (partial 730.. on front) as far as we can see (see photos).
Original Drive Train and wheels are present and work well. Complete with the Bell!
Train was designed to make a whistle sound when a lever on the front was pulled and to make "train noises" when it was pulled forward (internal spring is still present). As on nearly of these (98%), the rubber bellows is collapsed and non-functional (there is a site called Tri-Ang NL "https://www.triang.nl/locomotive.htm" that tells how to make a new bellows - they also give a detailed company history).
Has the front and rear bumpers. Excellent example of this 60+ year old toy! Please see photos for more details and condition.
