I have a Lionel War bonnet Diesel w/ rail sounds #621973. The train ran off the table & now the rail sounds don't work completely. When you put the train in motion, the diesel sound doesn't increase & when slowing down, you don't hear the brakes. I also have a problem running this train across the 042 switches. It arcs when crossing & shuts down & then restarts.

From the impact of the train when it hit the ground, it has probably damaged the sound system beyond repair. There are multiple problems that could've occurred, such as the wires breaking/loosening, or the sound box could have broken. There isn't a realistic way to fix this, really.

Even though it may not have been your fault, you should try to prevent things like this from happening in the future.

As to the 042 switches, this is likely the same problem. You can order replacement switches online to test them and make sure for relatively cheap, however.

There is hope for you, however. Go to the link below to go to Lionel's customer service page. There, you can find replacement parts and service stations that can replace/repair your train for you, for a small price compared to the value of the train itself. Good luck getting it fixed!
