I believe you are able to control multiple trains with the app using only one device. You don't need a cellular network to download the app, you can download it via a wired or wireless network, depending on your device. For the past Christmas, my wife bought two RCA tablets for our twin daughters, $99.99 ea. at Wal.... , in January, without us know why, we were refunded $199.98. Our daughters use them to watch YouTube, play games, read and send email, even do some of their homework on them, and yes, security features are enabled. I'm going to running trains on them soon, and the tables are PINK!
LOL.
As for the CP Christmas train, Yeah Baby!, but the prices...for those prices, do it in Premier!!!!
It is my humble opinion that MTH is heading in the right direction with this catalog, at least for entry level RTR. It has raise my curiosity and anticipation for the MTH 2017 Volume 2 catalog a little more.
However, I don't get one small part or maybe my understanding of what a transformer is may be incorrect. On page 3, the set contents are described containing the wifi unit which has a power supply of 75 watts, as far as I can tell . It appears that the connection from the PS to the wifi unit is the same as the other MTH RTR PS and how they connect to the z1000 or z750 transformer controller. However, it states if you want to run conventional, you would need to buy a traditional transformer. Wouldn't you just need to buy the transformer controller and then use the 75 power supply that comes with the set? Specifically, you would buy the 40-750C versus either the 40-200 or 40-300?
