Tyco sesame street train set doesn't work

Sounds like you have a pair of gears in the wrong way around. You need the small one on the motive source and the large one on the drive to the wheels. The way you have them the large gear is on the motor and the small gear is geared up and ten to the dozen turning into a GT Racing Bus.

If your Sesame Street train engine is not responding to the remote, here are some troubleshooting steps you can try: Check the batteries: Make sure the batteries in both the train engine and remote are fresh and properly inserted. Check the connections: Make sure the train engine and remote are properly connected and paired. There may be a reset button on the engine or remote that you can press to reset the connection. Check the distance: Make sure you are within range of the train engine. If you are too far away, the remote may not work. Check for obstructions: Make sure there are no obstructions blocking the signal between the remote and train engine, such as furniture or walls. Contact customer service: If none of these steps work, you may need to contact the manufacturer's customer service for further assistance. They may be able to provide additional troubleshooting steps or offer a replacement if the train engine or remote is faulty.

You bought "the pen"?

What exactly are you talking about Mike? We really need more information (brand, model, pictures of the specific item, etc.) in order to provide an appropriate reply.

Thanks!

There are 2 wires from the transformer to the power rail screws on the track. Hook up the wires and watch the direction the engine moves when you move the lever to forward. If the engine moves in reverse, either swap the wires or turn the engine around on the track.

I had the same problem, so I watched the YouTube video again. You have to squeeze its left hand to activate it. Good luck!

Just plug the camera into the mac with a USB and see what happens.
Many cameras do not need drivers on macs.

Check the engine and transformer by taking the two wires from the transformer and, while holding the engine upside down put on wire against one side wheels and the other wire on the other sides wheels...that will tell you if the engine is at fault.

If you go to :
www.hoseeker.net
they have old catalogs and part numbers for Penn Line trains. Then try:
www.yardbirdtrains.com
for parts or a replacement motor or they may be able to point you to someone who may have the parts. Good luck.
