Spotted today - Loo-less for over an hour!

Today I travelled to Portsmouth Harbour (from Angmering in West Sussex) to have a look at the Spinnaker Tower and was dismayed to find that in amongst all the shiny, new(ish) Class 377 'Electrostars' that Southern uses all over it's network there are also a number of these in use…

313201 stands at Portsmouth Harbour station, 21/5/15

A class 313/2, one of 19 three-car electric multiple units dating from the mid-1970s. Day in, day out, they ply their trade up and down the 'West Coastway' from Brighton to Hove, West Worthing and Portsmouth Harbour… The latter being a 45 mile journey that takes around 80 minutes.

313201 stands at Brighton station with another Portsmouth Harbour service.

Whilst I acknowledge that anyone taking a four minute trip from Brighton to Hove may not have need of a loo en route, a 45 mile, 80 minute journey on a train without a toilet is a very different prospect and the Class 313s are sadly lacking in that department! During my journey one young mum was forced to leave the train with her pre-school son for him to use a station toilet and of course would have to continue their journey on a later train. Perhaps the Class 313s should carry adverts for TENA® and Huggies® products?
