The beloved 87th goes according to the schedule from the Tarot layout. While the driver kindly smokes / sleeps in the cabin on a "break", the maps tell him what time to start and how fast to move along the route. Not all of them, but the vast majority ride as they want, be prepared ;)
I do not understand what schedule the transport goes on, if it shows at the same time and arrives forever a couple of minutes earlier, a person comes to the stop in 15 minutes and stands freezing to find out exactly when he will be?, or does not arrive at all
