A First Ride In A Class 707 Train

I had my first ride in a Class 707 train today, from Clapham Junction station to Waterloo station.

I had expected a few glaring faults, as South Western Railway is dropping the trains.

But there are some good features.

  • Wide doors and spacious lobbies.
  • Free wi-fi, unlike the closely-related Class 700 trains.
  • Power scokets, unlike the Class 700 trains
  • Large litter bins.
  • Reasonably comfortable and spacious seats.
  • Walk-through.

And a few bad ones.

  • No 4G signal booster.
  • No full-length walk-through as two five-car trains, rather than one ten-car train.
  • A high step into and out of the train.

But they are certainly better than Thameslink’s Class 700 trains.

The current schedule between Waterloo and Windsor and Eton Riverside stations appears to be something like this.

  • Waterloo to Windsor and Eton – 54 minutes
  • Turnback at Windsor and Eton – 31 minutes
  • Windsor and |Eton to Waterloo – 56 minutes
  • Turnback at Waterloo – 9 minutes

Which works out at a very neat two and a half hours for the round trip.

So for a two trains per hour (tph) service you need five trains.

The timetable is written around 75 mph Class 455 trains, but the Class 707 trains are 100 mph units with a shorter dwell time at stations.

In each direction, there are twelve stops, which will give savings of at least a minute at each stop, due to the faster acceleration and smoother regenerative braking.

So assuming a minute is saved at each stop, that brings the round trip time to 126 minutes. Reduce the turnback time at Windsor and Eton Riverside and I feel it would be possible to do the round trip in under two hours.

Which would mean that the current two tph service would need four trains.

From Twickenham station, the route is fairly straight and this may enable more speed improvements on the route.

The Waterloo to Windsor and Eton Riverside service is a classic example of how running faster trains often needs less trains to provide the same or even a better service.

Conclusion

I could see trains taking forty minutes on this route.

With the possible savings on the Waterloo to Windsor and Eton Riverside service, you can understaqnd, why this is the first route to receive the new trains.
