A one-station extension east to Felipillo is also proposed, although this is outside the scope of the initial construction contract.\r\nAccording to the contract services should begin within 46 months of the start of construction. Initially, the line will carry 16,000 passengers per hour per direction (pphphd), although the design capacity will be 40,000 pphpd.\r\nA fleet of 21 five-car trains will be required to operate three-minute-interval services at peak times. The train fleet will be maintained at a 12-hectare depot at the eastern end of the line.\r\nLast year a consortium of Barcelona Metropolitan Transport (TMB), Ayesa, Spain, and Louis Berger, United States, was awarded a $US 32m five-year contract by Metro Panama to provide project management, coordination and technical assistance on Line 2.
