Out of interest, I checked to see how the 25 million annual ridership upon full build-out figure mentioned today compares to the Amtrak Acela HSR service and France's TGV.
For the 2024 financial year, the Acela had an annual ridership of 3.2 million.
For the 2024 financial year, SNCF's TGV's higher-service inOUI and low-fare OUIGO services had a combined annual ridership of about 130 million passengers.
Out of further interest, I wanted to see how the 25 million annual ridership figure for Alto at full build-out compared to current VIA ridership and Amtrak ridership.
For the 2024 financial year, VIA reported 4.4 million passenger trips.
For the 2024 financial year, Amtrak reported 32.8 million passengers.
If Alto hits the 25 million figure, it would be more than 5 times greater than VIA's total current ridership, three-quarters of Amtrak's total ridership, and a solid fifth of SNCF's total TGV service.
Out of further, further interest, I wanted to see how Alto would compare with the current Acela service.
