> A very important factor in railcar prices is the quantity involved. The MTA operates approximately half of the railcars in the USA and it orders far more railcars of substantially the same design than any other North American transit operator. In contrast, railcar manufacturers’ literature emphasizes the customization of their designs for each customer. See, for example, the following table from a Siemens Inspiro metro railcar brochure:[18]

> Manufacturers’ “standard” design metro cars, in many or all cases, would not be compatible with the NYC Transit system. For example, door locations and “high” floor levels vary on different models. Door location has increased importance today, as NYC Transit has installed platform barriers between door locations at several stations and is considering platform screen doors. While features of “standard” design metro cars could be customized for NYC Transit, customization would come with costs.

I think you misunderstood our point here. Of course, NYCT would need customizations of international rolling stock for things like the loading gauge, train car length, door location, platform height, electrification, etc. But as you can see with the Siemens Inspiro, these are aspects of the train that manufacturers specifically advertise as customizable. Everyone customizes these parts of the train, and so they are used to it and expect it.

Notably, though, things like open gangways or aluminum carbodies are not customizable. It is assumed to be the default. It's when you start to change these things that the customization costs creep in. It's when you start to overspecify tiny details of the PIS that the manufacturer has to invent their own bespoke software, entailing higher costs and inflexibility. And there are plenty of other tiny customizations that add up in the 819 page long R211 Technical Specification RFP.

> A very important and desirable feature mentioned in the ETA is that the next generation of NYC Transit Railcars should permit one person and fully-automated operation. All R211A and R211T cars are already being equipped for communications-based train control (CBTC); therefore, it should not be technically difficult or expensive to implement full Unattended Train Operation (UTO), also called grade GoA4 automation, in which starting, stopping and doors are all automated, with no need for a crew member on the train.

I'm not sure this as easy as you say, and would require retrofitting. The R211 RFP Technical Specification requires provisions for TPTO and OPTO, both under ATO, ATPM, or manual driving. There is no provision for UTO, so it would have to be retrofitted, even though that may not be technically too difficult (I'm not sure exactly how hard it is).

However, for something like the IBX that could be automated from day 1, you want a very different design from the NTTs. There should be no operator room whatsoever, with that room instead being used for more passenger space and a wide front and back window. This both increases passenger space, provides a really nice view, and helps in convincing the union that UTO is the only option, as there is literally no room or controls for a human operator. But this is fundamentally different from the NTT design, but is in line with many international trains.
