Hi, I have a the Bachmann trains HO Scale Santa Fe Superchief trainset http://web4.hobbylinc.com/gr/bac/bac00636.jpg which came with a Santa Fe FT locomotive. what I would like to know is if this wheel is what I need: Geared Drive Wheel-Older 8 Wheel Drive (HO B23-7) because I need to replace them.

Thanks in advance.
