    I recently bought an Athearn SD70 and its a nice locomotive. I got it to run with some Atlas SD60's in the blue Oakway paint scheme and found the Athearn is very much slower. I realise this is probably a scale speed feature but its quickly become a case of buy more Athearns or re-power it.

    Does anyone know if it can be re-powered and with what.
