I recently purchased a Rail King Brill Trolley 30-2512-1 with PS 1, at a train show. I have a couple of questions about this model. It says it comes with protosounds. Does that also mean that you can control it using a DCS remote? Also, in conventional mode, this thing runs really fast. Is there any way to slow it down? I got this model without instructions and I am having a heck of a time figuring it out. I know I need to get a BCR for it, but do I need to dive into DCS to get this to run at a more realistic speed?
