While I disagree with your assessment of the FLIRTs, they are not the only design that offers level-boarding. Across Europe, different designs with their own advantages and disadvantages are available with level-boarding at platforms significantly lower than the UK 915mm standard. Siemens and Bombardier were building level-boarding trains for NS more than 20 years ago.I was just thinking if went for 1.2m platforms then the trains wouldn't require a decent amount of the unit taken up by equipment in the passenger area. That is one of my issues with the FLIRTs, which can make them feel cluttered. 1.2m seems to be the standard for major infrastructure projects in the UK for example HS2 & Elizabeth Line.
The problem with 1200mm is twofold:
- Firstly, it requires every platform in the country to be rebuild at a different height.
- Secondly, 1200mm platforms either foul the loading gauge for freight trains (preventing freight trains from running), or have to have a much larger horizontal gap, which brings its own risks.
There is a reason 1200mm platforms are limited to parts of the network that doesn't see freight trains. Having different platforms heights across the country is the worst of all worlds, so sticking with 915mm is easily the best option.
CAF charged a lot for the level-boarding option when LNER did the procurement, for future procurements who wins will depend on the quality and price of the bids, if CAF were to consistently be the most expensive one, they simply won't win. CAF has build level-boarding trains for European operators for good prices, so I suspect they won't keep this up. I'm guessing in the LNER case, the reason for the big difference was that the 897 uses the exact same bodyshells as the 397, so was much cheaper on design costs.CAF charge an unreasonable amount for level boarding according to Gareth Dennis, hence most TOCs don't bother. Even with TfLs new DLR trains they have a floor height of 1025mm.
