Thanks to everyone who commented - the responses confirm what I
suspected which is that it will be something of a challenge but
timetabling can certainly minimise the risk of conflicting moves.

Are the plans to which you refer publicly available on the net? The
nearest I could dig out was an old post on the now defunct London
Connections blog from several years ago. The diagram doesn't have the
subtle detail to which you refer.

I haven't come across the plans on the net -- and my information could be
out of date, as it comes from the February 2000 MR.
