Aerotrain Stuck in Neutral

I have an MTH ProtoSound 2.0 Pennsylvania Aerotrain from 2001.

Time for a new battery??If it's white chuck it out.

Thomas,
      You can use a regular 9 volt battery just to test it out for a short time.

As Gregg says, it's probably the battery as the engine will not move from neutral if it doesn't hold a charge.

I am not an expert on PS-2 but I think the PS-2 battery is either a 5 volt or a 3 volt battery. PS-1 uses the 9 volt battery look-a-like 8.4 volt MTH battery.

Have you tried charging the battery while installed in the engine with an MTH wall charger for around 24 hours? That should fully charge your PS-2 battery. Track charging is too risky for long periods of time(my opinion).

Actually Lee, the batteries for the 5V PS/2 are indeed the same 9 volt battery as was used for PS/1.

This sounds (pun intended) like the speaker is bad. Inspect it fro flaking around the outside and do not run until new speaker is installed (bad speaker will blow the board).
