As Super mentions I have had some extensive research and repairing on the TnA Talking trains. I believe the ones you are working with are a bit different but I have had them apart a time or two as well.
The thread Super mentions specifically post 37 from Tramp has a bit more info on the components.

I will say they seem to run fine with out the extra resistors and capacitor. I have not had one die or anything from removing those and running. It should indeed give you the 4.5v.
Hope this helps, if you have any specific questions about putting it back together, please post some pics and I will chime in to try and help.
