It is essential for us to carry out regular maintenance on our trains and some of this is carried out at the weekend when we operate shorter trains in the suburban area. Where we have major events on the network such as Rugby at Twickenham we lengthen some trains to meet demand.
We will be introducing 10 car trains at Wimbledon in the near future. For this to happen, stop boards have been moved so that stop further along the platform to allow the extra two carriages to be fully accomodated within the platform. When we are running 10 car trains they they will stop near the bottom of the stairs.
The new automatic door at Teddington station is expected to be installed this Autumn.
I'm sorry to hear about your experience with the onboard announcements being incorrect. There are a number of possible causes for this to occur. If you are able to advise the guard directly or contact us @SW_Trains we will be able to get a message passed to the guard of the incorrect announcement which they can override.
