Having commuted on the GEML for a number of years on stock that has no A/C I recently noticed that all trains have black roofs.
Surely if they were to be painted white instead the carriages would be cooler and on stock with A/C the power use would be reduced.
The new London bus stock are red with white roofs so they don't get so hot, why not train carriages.
