Is it just me or is every Operator hedging their bets at the moment
Virgin ordered just 12 Avelia Stream, 300km/h but with tilt option, clearly don't really need tilt for London services, so is this a backup plan
Eurostar ordered 30 double deck Alstom 'Celestia' trains (Avelia Horizon type), and has 20 options. Without the options hasn't got enough to replace all the mid 1990s E300 and ex-Thayls red trains.
Trenitalia has added options to its ETR1000, initially adding 10, then more recently another 9, taking order to 74. It is committed to a base in Paris, having recently secured lease to develop depot, but of course could always use trains on other routes (not London)
Italio has just ordered 26 Velaro for Germany, but has 14 options which may or may not happen, and been no indication of where. They are all quad voltage so presumably could be extended to routes in multiple countries (and if intention was only to use them in Germany, why add all the complexity)
Renfe are trying to rush through an order to replace its original Madrid-Seville sets, but the quantity of 30 (with 10 options) suggests possibility of expansion. Apparently Siemens with Velaro and Hitachi with ETR1000 are only bidders for tight delivery timescale
SNCF ordered an additional 15 quad voltage Alstom Avelia Horizon earlier this year (taking total ordered from 115 to 130). That adds more capacity than the remaining older single deck TGV, so either there is expansion planned somewhere, or it allows number of older sets to pass to low cost divisions.
In May was announced that a Memorandum had been signed between Swiss Federal Railways, Eurostar and SNCF-voyageurs to develop Switzerland-London services, presumably this could potentially mean additional orders of Avelia Horizon trains for joint operation.
Sort of feels like Operators are targeting London (and if HS1-HS2 link goes ahead, maybe Birmingham or even Manchester), but making trains suitable for alternative services around Europe in case London isn't workable.
