Rail line re-routed away from coast due to climate change

The San Diego Association of Governments (SANDAG) is starting the next phase of a process to re-route its coastal railway line due to climate change.

The San Diego LOSSAN Rail Realignment project is considering potential new routes that will move the tracks away from eroding coastal bluffs. SANDAG has opened a 45-day period of public consultation, which will end on 19th July.
There are three proposed alternative routes, of which two were derived from previous conceptual studies and one was put forward by the public.

All of the alternatives include moving approximately 1.7 miles of the existing single-track route away from the bluffs and into a double-track alignment in a tunnel under the hillside.

For more than 20 years, SANDAG has led efforts to preserve the cliffs. There have been repeated disruptions to rail services throughout this period due to landslides, erosion and seismic activity.

The LOSSAN Corridor is a vital rail link carrying almost four million passengers each year. It also enables the movement of more than $1 billion (~£780 million) in goods for imports and exports across the US.

Any parallels / comparisons / lessons here - from the UK^▸ (United Kingdom) to USA or vice versa?

The LOSSAN corridor at $1 billion (~£780 million) in goods, the UK rail freight contributes £2.45bn to the UK economy each year, now if only the Dawlish route could generate £780m per annum .............
