I’d imagine we’ll see the same low level plug doors with traps that are on the new Midwest venture cars. Since the NEC doesn’t really need the automatic gap filler it makes sense to stick with traps on every door for added flexibility. Unless the low level plug doors won’t fit in a high platform...
Trap doors complicate operations at low-platform stations. Conductors need to walk the train to open the traps.
My vision would be that one end of the car would have a low-platform door with automatic doors/steps and on the other end would have a high-platform door.
With that layout... you'd have high and low-platform doors right next to each other on opposite cars, giving both options.
Maybe some of those high-platform doors could have wheelchair lifts to board passengers at low-platform stations without using the slow crank-operated lifts.
It doesn’t have to be earthshaking for them to not use Siemens. Another supplier could be just as good or better and come in with a lower price who wants the contract. Siemens does seem the best so far and has been tested on the NEC as a single test train along with Sprinters and Amfleet. Siemens has the most progress so far. Sumitomo and Nippon Sharyo failed on tests for California and they went with Siemens Venture. As of now I agree that Siemens is the best choice but if someone says I can do same project with same or better quality and can come to cheaper price, I could still see another supplier in the running but time is running out as it would be nice to see the supplier finalized this summer and for production to begin. The Siemens venture if chosen would be better than the Amfleet I they will replace.
I responded to you in the other thread... but you misunderstand how this works. That whole process of companies offering to do the "same project with same or better quality and can come to cheaper price" has already happened and the winner was Siemens.
What will happen between now and this Summer is that Amtrak and Siemens will be hammering out things like design features, various requirements, and negotiate terms and conditions that are fair and assign risks to the party in the best position to control them.
This was one of the big learnings from the original Acela order... unless both parties have a very clearly defined vision of how the final train will look and operate... you end up with a bunch of change orders that add time and cost to the project. The
Amtrak inspector general has a good nerdy read comparing the problematic Acela order with the much smoother Surfliner car order.
Now -- why call them the "preferred bidder" and not the "winner?" The ink isn't dry on the contract.
Say that Siemens refuses to add a "must-have" feature for Amtrak, or Amtrak demands a contract with terms and conditions that Siemens feels are unfair. Talks could break down and could be called off. That's why they're the "preferred bidder."
That said, Siemens and Amtrak have reached several contracts in the last few years. The chances of the contract talks breaking down seem very, very low.
I have questions:
- Can passengers move freely between a semi-permanently coupled set and whatever is coupled to its end?
- Do the Siemens cars need to be joined and detached in a shop, or can it be done online with passengers aboard?
My understanding is the Midwest sets have traditional gangway/diaphragm at the ends so that the semi-permanently coupled married pairs can be coupled to other Venture/Amfleet/Horizon cars. California has gone with a completely closed system... a cab car on one end of the set and a blank end on the other (with a provision to add a gangway in the future).
I get the impression that the Siemens cars can be joined and detached anywhere if necessary, but it would be easier in a shop. It's not something you'd want to do online with passengers aboard -- unless it was an emergency and a car needed to be set out.
