F7 A&B Decoders

[Don Stafford]

I would like to know which Bachmann factory installed decoder is installed in the F7A & Bs and is is possible to obtain an information sheet from Bachmann.  I would like to be able to speed match and control these as accurately as possible.  Thanks,
Donstaff

All of Bachmann's "DCC On Board" (non-sound) decoders have the same functionality. They have very limited features as far as speed matching goes - https://www.bachmanntrains.com/home-usa/images/44913_Decoder_IS.pdf
