I have received complaints from constituents about high temperatures on New Bus for London vehicles. Has TfL undertaken any assessment of the cost of retrofitting these buses with fully-functional opening windows? If not, will you ask them to do so?

The New Routemaster is fitted with an air cooling system that is designed to work with closed windows. Assurance checks were conducted during warmer days last summer and the system was found to be at least as effective at improving comfort in the upper deck as conventional double deck buses with similar systems and opening windows.

TfL continues to look at modifications and technologies that might provide bus passengers with greater comfort during spells of warmer weather. Some current trial initiatives include improving ventilation on buses on route 73 and overlaying solar reflective film on top of windows to see what the potential impacts on heat gain might be.

TfL is satisfied that the current air cooling systems work as designed, and can be complemented rather than undermined by other changes.

It would not be desirable to make air cooling units work harder to nullify the effects of warmer air entering the bus through opening windows. For this reason, there has been no assessment of costs for retrofitting buses with windows.
