dungeoneer, here's a map that may be useful to anyone who doesn't have the official Mornington Crescent rules with the Temporal Variations 1890-2857 appendices. Due to its size I've posted it here, rather than as a comment in his journal. Some reminders:- The multiple time paradoxes of 1963 make all non-linear transits problematic.
- much of the underground system in the Holborn area (which technically includes Mornington Crescent) is occupied by Yeti circa 1971
- The dinosaur invasion of 1980 disrupts surface routes
- The Cyberman invasion of 1985 disrupts all non-cyclic routes.
- Mornington Crescent is destroyed during the Dalek Invasion of 2150
Hope this helps!
