Since the home router is still there, I'm suspect if the phone was bouncing
between the two routers. If so, it would account for this loss and restore
of connections. As you move around, the phone would see one router as the
better path and then it would change which might be better. Also if the two
routers were overlapping on the Wi-Fi bands, that is more interference to
sort out by the phones. Last would be if they somehow had the same subnet,
if the train router was standalone, this could be the case, and if so, it
would get very confused when switching between them.
So, what is the Wi-Fi band and IP range of each router?
