Alstom, Transmashholding, and Vermerkiper Engineering, Argentina, which is likely to act as an intermediary for another manufacturer, were confirmed as bidders on December 26. A Bombardier-Siemens consortium, which was reportedly preparing an offer, decided not to submit a bid following a reduction in the contract size.\r\n\r\nThe initial order for 169 trains was scaled back following the suspension of the Buenos Aires RER project in June 2018. The Argentinean government took the action after reaching a bailout agreement with the International Monetary Fund (IMF), which required a reduction in the country\u2019s budget deficit. The project was expected to be developed as a public-private partnership (PPP).\r\n\r\nCRRC, Hyundai Rotem, Mitsubishi, KBR, Stadler, CAF, Materfer, Emepa and Benito Roggio, all of which participated in an information session hosted by the Ministry of Transport, declined to bid.\r\n\r\nThe new trains will initially serve the electrified San Mart\u00edn and Roca lines and later the Miter line. Around 70km of the Roca line between Constitutuci\u00f3n and La Plata, Claypole and Bosques, and Berazategui and Bosque, are electrified while a project to electrify the 76km San Mart\u00edn commuter railway is underway. The work is funded by a $US 400m loan from the Inter-American Development Bank and $US 122m from the Argentinean government.\r\n\r\nThe contract requires 20% of content to come from local sources, with Alstom and TMH having the advantage of local production facilities. However, the contract would likely require an expansion ofAlstom\u2019s facilities at La Plata and TMH\u2019s at the Mechita workshop.\r\n\r\nThe new trains will feature air-conditioning, passenger Wi-Fi, LED screens for passenger information, internet-connected CCTV, automatic doors, air suspension and automatic braking.\r\n\r\nDelivery is set to commence in late 2021.
