I currently use 2 TIU's on my layout. With a planned expansion, I will need to add a 3rd TIU. I also have 2 Wi-Fi adapters connected to the TIU's. I have not been very happy with using a phone or ipad to control the trains, and I prefer to use the DCS remote.
I am concerned that even if something is developed to allow the new WTIU to accept commands from the DCS remote, will the WTIU be able to be added as a 3rd TIU.
I will continue to buy MTH rolling stock and accessories, but no more engines until the future of DCS hardware and software is better defined and communicated.
