Hi   Just received my On30 trench loco, but runs horrible on DC.  Are all the locos like that? Have tried various DC controllers, mostly filtered. Works OK on DCC but I only have DC at my home where all other sound equipped Bachmann locos work fine. Bachmann service dept has offered to exchange but there seems no guarantee it will work on DC (?) . What can I do?   Some think wow sound does not work on DC?
