"If it works in other industry's why can't it work in rail" :D except it often wasn't really working that well in other industries and they moved at just the point availability of skilled IT staff went down. Even CAF prefer to have their key suppliers within day trip range Alstom software is...

Which is why I said Coradia PV in the original post but you ignored that. Polyvalent effectively translates as Multi-mode The divestment of the "Coradia Polyvalent" brand was a specific requirement (along with the IP) of the EU competition commissioner in approving the Alstom Bombardier...

Correct which also includes some current products. The hardware (loom control processes) isn't the issue but the Bombardier moving software to Bangalore Alstom can do the software variations well unlike Bombardier (Rail). That was largely the Bombardier philosophy which was let down but the...

It is a bit more complicated than that especially as philosophy has changed/adapted post Bombardier. Most trains belong to a belong to a final assembly facility linked to platform design. There are technology centres of excellence for components /shared architecture design which often feed...

As I wrote few pages ago Alstom has had to dispose of two continental MU platforms (including brands and license the IP if they they continue to use themselves or hand over the IP if they don't) for one ex Alstom France (Coradia PV, multi-mode EMU) and for one ex Bombardier Germany (Talent3...

And how would that work with regenerative braking which all the units in this area use? (Saving operators many £££s) 1713427818 345 are 5-4 split with the middle vehicle being trailer so no traction power need there anyway. 701 is 5+5 Software is used

As part of A-B merger Alstom had to agree to divest certain plants, related IP (including product name rights) and assuming some key staff too. This included some of a continental sister platform to Aventra but not Aventra hence the need for the new product family name and regenerating a product...

... but around Manchester airport is the part of 2B that is included in NPR.

Brixton southbound if the stopping point isn't changed (which is do-able if a little unusual to have the door not opening at the front rather than the back with SDO)

Herne Hill platform are currently 9.5car length, especially if you get rid of the requirement for the networker/455 DOO monitors (which is the big problem). SWR's ASDO system would address precision stopping requirements and any junction blocking issues for the 10th car. A number of the other...

No the ideal is 12 car on Charing Cross or Cannon Street if SDO were to be fitted (in the previous tender) or 8car for Victoria or Blackfriars (10 car with SDO would work for many of these station as there are plenty of easy extensions.

They learnt... (do the Plaid models have gearing?) Road vehicles have higher rolling resistances than rail which has pushed most road vehicle manufacturers towards PM motors as the primary motors which run into the same issues as traditional DC motors or older single phase synchronous AC motors...

How many non hybrid electric vehicles is the relevant comparator as we are talking about electric trains. Cars: Tesla - No BYD (apart from the driving school car as this has to have manual transmission with fake stall for driving tests!) - No Lucid - No HGV: Tesla - No MAN - No Volvo/Renault -...

I was trying to keep things simple as it isn't used in most case (only very high speed range) but it isn't used in most cases so I didn't mention it. 1713084452 50% You would have more at a same but different gearing, you wouldn't switch Freewheeling is called coasting and virtually all...

Weak field is unnecessary on modern 3 phase AC systems with asynchronous motors. 1713022362 Plenty of sub 100mph, 100/105/110/115mph south of Bedford. The third option on modern 3 phase AC systems (which have less gearing issues than older DC or single phase AC) is more power (to increase...
