Here’s another basic noob question that I suppose, if I put the correct combination of words into a Google search I could find the answer to, but I figured I’ll just ask here: Are the DCC sound/light functions the same on all locomotives or do I have to keep sheets of instructions for each loco I buy and refer to each one for the different functions? (Or does it change by manufacturer?) So I made my first DCC locomotive purchase, a Bachmann EMD-SD45. It was cheap and I just needed something to test out my NCC PowerCab Starter Set and after a few jittery fits and starts and after running it for a few hours now it’s actually working pretty OK. For the basics I don’t have to remember anything because the PowerCab has specific buttons for horn, bell and lights but according to the instruction sheet that came with the engine there are a few others; F2-Airhorn, F3-Short Airhorn, F7-Dimmer and F8-Mute. Also, F4-Airbrake is supposedly not available for the SD45 yet when I press F4 there is some sort of change in the motor sound and the loco comes to a fairly quick stop. So are these functions the same for other diesel locomotives, will I have to save the little instruction sheets for each and every one I buy or will they all be the same? Also, is there a way to use the PowerCab screen to see what different functions might be available for any particular loco I eventually get?
