PS2 5V board, maybe check the capacitors, ensure the battery is good.

2001 engine now 21 years old, while the engine is likely good mechanically, that may or may not be the electronics giving the death rattle here. I hope that is not the case but again one of those know what you have kind of situations. PS2 5V can have problems and failures at a higher rate than some other control boards.

The ones I've seen fail (and it's usually a blown cap) were made in 2000-2001. The 2002-2003 5V boards seem to not suffer from that as much, although it's really random chance. I've seen more RK steam and diesel failures with PS2 5V than Premier steam as well (except the Premier FEFs, which fail frequently). I can't say why.

All my stuff is either PS2 3V, PS32 boards (things I've upgraded) or PS3. The oldest PS2 3V locomotives I have are about 17 years old and are running fine.
