@West Side Joe ' Lou above is correct. Each sound file location is a little different on each train. However, I did notice that most of my PS2 3 volt subway sets had the "this is a number XX line bound for YYYY" announcement at the same engine sound location (usually engine sound 10). I would recommend scrolling to "more" using the S5 softkey and then scroll to and try each engine sound in your subway, then move it to the top 4 locations (I.e. 1-4) (the "move" function is located at softkey S2 when you are in the "more" directory) . If you do this, when you start up your subway train with your DCS system, the initial screen will immediately have your key softkeys on display in the handheld remote. For example, in all my subways, I moved the Trolley Mode function into the first position (soft key designation "MTC"). Now I can access it without having to scroll into "more" and its initially on my screen when I call up the train. I moved the engine sound that announces the line and route (I.e "This is a number 7 Train bound for Times Square") into the second position, etc. I usually place extended startup and shut down softkeys in the next two locations (SSD and SSU). Other key (to me) sounds were also moved up to positions 5- 13 (I believe) and appear in the next 2 screens of the DCS remote for all of my engines. When I want to hear the various stops in my subway, I just click on the trolley mode (MTC) which is now located in S1 for all my subways, and go into "Manual Mode". Then I just keep clicking through all of the announcements. When you hear one you like, hit "arm". then, when you manually stop the train in front of your station, it will play that station stop announcement and accompanying accent sounds. Play around with it, have some fun, and you'll see what i mean. MTH subways are a blast with DCS.
Ironically, just an FYI, on my PS2 MTH R1 train, there is no engine sound for the line/route. However, if you start up the train with extended startup (SSD softkey that I have moved into one of the top 4 spots), it announces "this is an A train/ 8th Avenue express (or words to that effect). This is the only subway train in my fleet without an engine sound announcing the line/route that I can access in DCS. So, if you don't find that on your R!, don't be surprised. I think I moved one of the more popular station stop engine sounds to the 2nd position for my R1, like 42nd street.
