Can someone please mark the 4 tunnels on the DHQ - MJY section as spots for which photos can be added?
As per my understanding the tunnels on the North-South line (with all it's twists & turns) from DHQ to MJY are marked as 1A, 2A, 3A and 4A respectively. I am not aware of how the tunnels on South-North line from MJY to DHW are marked, presumably they are 4B, 3B, 2B and 1B?
Thanks in advance!
