Damaged the electronics running DC instead of AC+

I do not think so, it rectifies the incoming AC to DC.  SO the DC would just be filtered.  Did it ever run on AC?  After the 2 dings, do you lower voltage to less than 10V to come out of reset?  G

Thanks for your reply! I first run it on DC. Then on AC and it never comes out of the reset state. I have measured the AC voltage coming out of the transformer with a voltmeter and I follow the instructions with slowly lowering the speed control to 0-position and then turns it on again to higher speed control positions. I use an old Märklin transformer maybe it needs to be an MTH/Lionel transformer? I guess I need it anyway to control the bell, horn, direction?

Magnus, 

You could try putting the wiring back to original in the street car. Then try AC power again. Disconnect one of the wires from the transformer to the track. Then power the transformer up. Then  touch the disconnected wire to the terminal remove it again after a few seconds and repeat. The street car reverse unit should cycle. 

Normaly reverse unit cycles through 3 positions. Forward, neutral, reverse. Some start in neutral then forward, then neutral, then reverse. Every interruption in power cycles the unit.

 P.S. I would go with a MTH transformer.

I don't know whether this will be of any help.
I have a Railking 2503 PCC Street car, which I thought was their first offering.
The instructions state that it has a QSI DCRU electronic reverse unit, and it is upgradeable to "Protosound Digital Sound and Train Control"
There is no mention of it being AC only.

Did you replace the battery with new?  IF this is original PS-1 and has the original battery, good chance the battery is dead and the engine may even have a software conflict now.  IF this is your first PS-1 engine, best to take it to a tech who can test and reprogram the engine if it scrambled.  IF you have other PS-1 and know how to operate them, go through all the normal steps, new battery, reset 18 etc...   G

Thanks Nick but it did not work, I will try with a MTH transformer.
Cheers!

AC is the version, I am pretty certain, it has an AC/DC rectifier in it.

This one has the BCR (capacitor battery) red. I have also tried with a regular 9 volt battery.

Well, can be simple software glitch requiring reprogramming, bad board, bad chip.  Pull chip and reseat flush with PLCC holder.  Use the tool for chip removal.  G
