Hello item is from my personal collection and I will be selling several rare hard to find in great condition vehicles and all of my items work and run superbly on HO scale electric tracks. The fire truck lights and bell work great also works great in reverse, this is why the fire truck has to sets of copper connections front and back (see photos for more details) Good luck bidding. You have any questions please message me through eBay and I will do my best to get back to you quickly. Also I am going to give you a tip for all your electric vehicles that you have and this is a friendly reminder. I recommend a light sanding with sand paper on the copper connections (the shiner the better the connection) if you have any issues with connecting to track and speed and this way in the future you know, you don’t always need to replace the copper connections just clean them by hand with sanding paper very gently to get the shine back.
