HO,
This is a Bachmann DCC on Board locomotive, yes? If it is, then it has a low-end Lenz decoder inside it.
Because one has sound and the other doesn't, you'll need to match the non-sound Geep with the sound F9B because, generally, sound units take more voltage to get them going. That means dialing up or down the startup voltage (CV2 or V-Start) on the Geep so that it starts out at the same time as the F9B.
What kind of DCC system are you using?

thanks Tom for the Lenz brand name. I am using MRC prodigy advance square.
Sorry but what does Geep mean. If I can get these two engines consisted, I want to buy addiitional F9B units to go with my other Bachmann DCC /no sound locos, I have the 5003;5009( Red white), and 8205 8210 Grey and Maroon.
HO noviceSorry but what does Geep mean.
Sorry for the confusion, HO. "Geep" is the name given to GP locomotives.
Also, just a note of clarification. Lenz (the name of the inventor of DCC) actually does make some very fine decoders. Their Silver- and Gold-series decoders are just excellent and extremely smooth - although pricy. The quality of the ones that Bachmann installs in their DCC on Board locomotives, however, are only so-so.
