For those of us (me included) who have commuted in the heat, you will know that some of the trains were unbearable without air conditioning. Over the last month I have spoken to the operators to get an update on when we will be replacing the older trains, and I have good news.
The older stock trains (such as those that start at Tunbridge Wells) are gradually being replaced at the moment, and I am assured by next summer, they will have all been replaced by trains with air-conditioning.
This will then leave Metro Electrostars (which are a lot newer). While these trains do not have air conditioning, they do have a pressure air ventilation system which replenishes the fresh air in the carriage.
I look forward to the trains being more bearable next year on hot days – for both commuters, as well as those who are visiting family and friends or planning days out.
