According to http://www.londontravelwatch.org.uk/get ... hp?id=2224 LU are planning to cancel two Olympia trains in the AM peak to allow an extra service to Wimbledon. Looking at the Journey Planner this appears to be happening next Monday (12th).

So anyone planning a 275 attempt would be well advised to avoid Olympia in the morning.

Oh, arse-biscuits. Thanks for the heads-up regarding this. Not sure if my route involved an AM Olympia, but I'll make sure to worry about it after I've put some rough times into JP.
