The first Big Hauler ten wheelers (4-6-0) were battery powered sets using 6 D cells in the loco. They had plastic wheels to run on plastic track. They then changed to only track power (metal wheels on the locos) and have been that way ever since. There are five generations of the drivetrain on the track power locos. The fifth and latest is the best.
I don't think the set with the tender labelled "Holiday Express" is a Bachmann product. Its probably New Bright or similar.
Pictures would be very helpful to figure out what you have.
