^I may have lost the thread on why there have to be two variations of Coach and two of Business Car, but taking that as read, it's apparent from the extra short version trainset that "A" cars are all that is needed to equip a trainset with all the prerequisite accessibility, technology, and service delivery equipment. The "B" cars may augment that, but one assumes that the "master" version of everything important is in the A's, and the "B" cars are fill-outs.
That leads one to think that the "B" cars ought to be generic and most easily convertible from one configuration to the other. So, if the distribution were found to be sub-optimal, it would be most practical to shift from Coach B to Business B or vv.
So long as that's roughly true, then I wouldn't worry about getting the initial distribution exactly right. Changeovers will be pretty doable.
I don't know if the configuration of any of the cars is publicly known, but if I had to guess (it is just a guess), the special features of each type are as follows:
| Car type | Class | Services | Trainsets |
| 1A | Economy | Galley | All (2x Extra Long) |
| 1B | Economy | Accessible (+ bike rack?) | Short, Long & Extra Long (2x Extra Long) |
| 3A | Business | Accessible | All |
| 3B | Business | Galley | Long & Extra Long |
| 4A | Economy | Accessible, Cab | All |
This would mean:
- The Short and Extra Short trains would have the business car use the Galley in the 1A car (presumably at the front of the car) and there are accessible seats and washrooms available in both classes of service (the short would have a second economy accessible car).
- The Long train would have separate galleys for business and economy and the same number of accessible cars as a short train.
- The Extra long train would add a second economy galley and a third economy accessible car.
One has to think that the chair frames will use common components, even if the cushions and backs differ. One hopes that moving between 2-2 and 2-1 seating doesn't require rebuilding anything structural, and wiring etc is compatible.
Given that the seating in business class is 2+1 but in economy it is 2+2, there is a good chance that the seats are wider in business class. The common areas would also likely be different as the washrooms might be appointed differently and fewer passengers means they may need less luggage space. The wiring for task lighting and power outlets would also likely be different for the different number and configuration of seats. So while the shell might be the same, there are likely significant differences to the interior, which would make conversion a bigger job than just buying some extra seats and reupholstering the existing ones.
I expect Siemens and VIA will have thought this through.
That is certainly my hope. The fact that VIA has published diagrams (albeit low resolution) of the different car and train configurations, I expect they have been having a lot of discussions behind the scenes.
