Air-conditioning of metro carriages would therefore be necessary, for which purpose BKV held a symposium last October on potential manufacturers specializing in air-conditioning equipment for railway vehicles and presented the characteristics of the carriages.

However, air conditioning would also require the permission of the Metrovagonmas, which is carrying out the modernization, as the installation of the equipment has serious warranty implications.

It is too early to rejoice, because if we can believe the previous press reports, full air conditioning can be realized by next summer at the earliest, but the current development can be booked as an encouraging first sign.
