I just purchased a MTH 30-2159-0 and it looks like it has never been run. I opened it up to see what type of battery was in it, white or green, but I did not see a battery. I did not see any wires that are not connected to anything. I looked at the instructions that were in the box and also on MTH web site and they talk about a battery and how to charge/change it. Did some of the early powered RailKing engines not come with a battery? Everything looks like it is there, motors and all the rest, brand new looking. I did not power it up yet, too late in the day. Just curious if some did not have batteries and the instructions were wrong.
Thanks
