Not just home PC's though, it will also work on web enabled PDA's (not
many
around now, but this will change). Imagine arriving at Paddington and
being able to find out if the next Eastbound train will be a H&C or a
Circle!

True, however the page layout is very un pda/smart phone friendly, it takes
a lot of expensive gprs data to download some simple information. Otherwise
it would be good for making journey decisions, especially on the sub surface
lines.
