I start and run my TIU/WIU on only when running trains. This means for each operating session I need to wait several minutes for everything to boot up, wait for the DCS internet to start so my iphone can find the network, etc. Does anyone just leave their TIU/WIU up and running all the time? This would reduce the amount of startup time when its time to run trains. As time goes on I'm finding the startup process is killing the spontaneous running of trains for a few minutes here and there.
