I having a small quirk with the DigitalTrainModel GP30s.
I can run them just fine in scenarios, and they work great. But there is a catch.....
When I try to control the locomotive using they keyboard, nothing happens. For example;
If I press the space bar to blow the horn, the horn will not blow, or if I press the B key to activate the loco bell, the bell will not activate.
I was just wondering if there was a fix to this somewhere, or if there isn't, is it simple like editing codes in each loco's bin files?

I've never had an issue like this before, and various searches turned up nothing on the issue.
BTW, the GP30s I have I bought from the old DTM store when it was active.
If there's a fix, please let me know, or let me know how I can fix it myself.

Thanks,
Noel.
