Thanks!
Btw. for other tips, not only that M, N keys when building roads are useful, but also what is good to know is that when you for road lines click on the station icon instead of the station shelter on road, game balances automatically, where to put the line according to current usage for the grouped stations. So if you have BUS station at the beginning of intersection from different angles, and you click on icon, the usage of particular stops can switch, when you add another line to this station.
