Its not so much that it takes command from the center rail, but how DCC and DCS transmits the signal. DCC (and I believe DCS) utilize a repeating command queue, where the last command to a loco is repeated to ensure the loco received the command. ( In case the loco was traveling over a switch or other part of the track where rail signal was broken up and not able to be interpreted.) If you attempted to use bluetooth within the presence of a DCC signal, bluetooth would essentially be ignored because the DCC (and likely DCS) signal would continuously override any bluetooth command received.
So you couldnt utilize bluetooth while those others systems were present. If they werent present, then bluetooth could be made to work, but now you're talking about adding a bluetooth receiver to every loco, where only a subset of users would use it, as DCC and DCS already have both wireless and wifi capabilities.
