London Northwestern are making a number of changed to their services into Euston and from 19th May there will be a new timetable in place. Originally there would be no change on the Abbey Line timetable however because of the Abbey Line arriving at Watford Junction at 6:30 with the revised connections would have meant people getting onto the 06:48 train which arrives at Euston at 07:10.

Working with London Northwestern we have managed to get the first Abbey Line train timetabled 1 minute earlier which means that it will arrive at 06:29 so it will be possible to catch the 06:34 which arrives at Euston at 07:01. As a note the late change to the Abbey Line timetable is not currently included on their website, however details about the trains into Euston can be found here.
