The Santiago – Valparaíso passenger rail project has entered another period of uncertainty. This follows the end of former president Gabriel Boric’s administration and the arrival of José Antonio Kast’s government in Chile.

Project background and route plan

Under Boric, the scheme was presented as one of the government’s flagship rail initiatives. It was designed as a medium-speed passenger line between Santiago and the Pacific port of Valparaíso. The journey time was put at around 90 minutes. In addition, that time could be reduced further. This would come through a 16km tunnel between Tiltil and Limache. Still, the proposal has already seen repeated delays and false starts.

Investment plan for the Santiago – Valparaíso passenger rail project

The total investment was estimated at $US 3.82bn. It was to be carried out in two phases. The first stage was valued at about $US 1.32bn. It would largely use the existing 187km line. Also, that line would be electrified, upgraded and realigned. The later phase would cost $US 2.12bn. At the same time, it would involve major new infrastructure. This phase would include the new tunnel. It would shorten the route to around 120km.

New government reviews alternative proposals

During the final months of the Boric administration, progress on the project slowed significantly. Meanwhile, potential bidders raised questions. Separately, rulings from the national comptroller also concerned the project’s structure.

Martín Arrau worked on infrastructure policy for Kast’s presidential campaign. For example, he said the new government could re-evaluate private proposals. These would link Santiago and Valparaíso. He argued that the route proposed under the Boric administration is “not very viable.”

For now, the Santiago – Valparaíso passenger rail project remains at an impasse. The new administration is reviewing transport investment priorities. It is also assessing whether to continue, redesign or replace the scheme with alternative proposals.
