Hey I need a new chip for my polar express lionel engine the old one got fried at one small part and won't go forwards it's the piece u4. Know where I can get a new chip for it and don't say the Lionel site I tried.
The IC may be custom made for Lionel, and therefore unavailable. There may be other parts that burned out but may not show any visible physical signs.
Get another board is the best advice.
