The frequent TGVs from Paris to Lille have a top speed of 300 km/h despite the only 216 km between the two cities. In terms of "effective velocity" this train covers the distance in precisely one hour - which is very convenient in terms of scheduling. Secondly, and more seriously, I'd strongly warn against committing an error (well, in my view it's an error) that has dogged the German ICE system. Even if one has to "start small" then one should definitely "think big". The German planners repeatedly started by planning for a line between two neighbouring cities whicl clearly having in mind a larger, trans-regional network to follow some day. Never mind what they had in mind! Immediately the discussion got seized by special-interest pleaders howling that "oooOOOOH!! But there's only 200 km between those two cities! Surely it cannot matter whether it takes 55 minutes or 1 hour 5 minutes?" Well... yes it could. Because when, later, one tries to knit together a more serious HS network between a handful of cities then a loss of time of 10 minutes here, 10 minutes there begin to add up. Thus, one should preferably never pander to local interests if one has a national (or, in the US, state wide) solution in mind.priamos wrote:Given that only half the money required has been allocated, the temptation must be to scale back the project . Bearing in mind the short distances between stops, the 168mph capability from expensive TGVs isn't needed. And 16 daily trains each way (1 an hour?) won't provide a great financial return from an electrified high speed line.Chafford1 wrote:Using the Jet Train or electric TGVs? I hope the latter.If I were a US politician I'd be loath to go for the Jet Train: Bombardier has developed a new generation of electric HS trains (the launch client is China - not Canada...) and is no longer marketing the Jet. If anyone bases a "modern" HS line on that old train I predict the press will be unkind to them. That said, if you look at the home page of the Florida HR Rail authority the construction times the foresee for Tampa-Orlando look incredibly tight (four years, start to finish). Seeing as it normally takes around 15 months to get the electrical system up and running, I fear that they may have in mind a "scraped solution".
This adds up to the following: if the Floridans are SERIOUS about eventually having a state-wide network connecting Tampa, Orlando, Miami, Palm Springs, Jacksonville and Tallahassee, then.... they should make sure the tracks between Tampa and Orlando are optimised for truly high speeds and with 25 kv electrical catenaries. Otherwise IMO they're going to regret it later.
