Faster than sensible

with 3 comments

Italy’s transport ministry and railway safety agency have rejected plans by infrastructure manager Rfi to increase maximum linespeed on high speed tracks from 300 km/h to 350 km/h. The story was covered by la Repubblica on 28 May (in Italian).

The decision was guided by concerns about safety (in particular, flying ballast), upgrade costs, possible increases in maintenance costs for the infrastructure and energy system, and lack of evidence that greater speed would provide greater punctuality.

It might be worth bearing in mind that many of the trains operating on the Italian high speed network are limited to 250 km/h in normal service, for example, the Nuovo Pendolino units ordered by private operator NTV.

The difference in speed between a 350 km/h train and a 250 km/h Nuovo Pendolino would have potential implications for capacity. In the UK, the capacity of the Channel Tunnel Rail Link is more limited by the botched design at St Pancras, than the speed differential between Eurostar and Javelin trainsets, but to be frank, HS1 is a bit of a dog’s dinner from start to finish.

  1. On the new (changes for Thameslink) time table, Nottingham to London St Pancras takes 1hr 40 min off peak, but about 2hr on peak. Presumably, this is due to loss of half the platforms at St Pancras to HS1. In theory, could HS1 be backed out of St Pancras, to connect to CrossRail somewhere to the east?

      • On the information available, the Midland Main Line long distance offer seems to have been somewhat deprioritised, to support more London commuting from certain localities, but not others.

        The possibility of using Crossrail as a link to HS1 was briefly discussed in a blogpost from March 2016.
