Madrid plans to spend more than €2.8 million renewing air-conditioning equipment on the 2000-A trains that run on Metro Line 1. A forthcoming tender will replace all condenser and evaporator units, which release heat from the train and cool its interior.

Metro said prototypes have been designed with Spanish technology specifically for these trains. Separately, it has a four-year contract worth about €3.5 million to maintain cooling systems on trains serving Lines 1 and 5.
