Well, lets see. First, I feel it is important to keep in mind the need for financial efficiency onboard Amtrak trains.
Augmentation:
Sleeper augmentation will be done other ways.
1) 25 standard Superliner coaches for the same reason.
Spares:
1) 6 Sleepers (LA, EMY, SEA, CHI, NOL, WAS)
2) 6 coaches
3) 6 diners
Reasons: You don't need a spare lounge- the diner can do that. You also don't need spare trans-dorms because in the pinch, you can use a standard sleeper.
Additional routes:
I am going to assume some additional routes that Amtrak has aluded to. 2 train sets would be required to comfortably turn the CONO into the City of Miami. The Desert Wind and Pioneer make sense. A North Coast Hiawatha is less sensible, but I suspect certain states would be willing to partner with the feds to make it a reality. I also say that DW and Pioneer should combine into the Desert Pioneer at Denver and produce a second frequency between Denver and Chicago. I also think that trans-dorms are a silly idea. A Baggage/Dorm/Sleeper with the rear part of the crew lounge being for baggage on these short trains makes more sense.
So you'd have the following consist for the Desert Pioneer: P42 (P), P42(DW), Bag/Dorm/Sleeper (DW), sleeper (DW), CCC(DW), coach (DW), Coach (DW), Coach (P), Coach (P), CCC (P), Sleeper (P), Bag/Dorm/Sleeper (P).
CONO: P42, P42, Bag/Dorm/Sleeper, Sleeper, Diner, Sightseer, Coach, Coach, Coach.
NCH: P42, P42, Bag, Trans/dorm (from other trains), sleeper, sleeper, diner, SSL, coach, coach, coach.
Now, the CCCs are already there, so diners would be ordered to displace the CCCs from the TE and CONO. You'd need 6 Desert Pioneer sets, 3 COM sets, and 6 NCH sets, and a spare sightseer
1) 15 Bag/dorm/sleeper
2) 27 sleeper
3) 52 coach
4) 21 diners
5) 9 Sightseer
Additional car types.
Several routes running superliners justify these two car types. The first car is an all-bedroom first-class lounge car. It would run on the SWC, CZ, GSL (Nee TE), EB, and CL. The upper level would be all bedrooms and the lower level would be a comfortable bar/lounge set up for first class passengers. 35 cars would be required to meet the need, I think.
The second one is a sort of couchette car, if you will. It is a Superliner sleeper, but the upstairs bathroom, and the luggage rack (will be moved over to displace a pair of bathrooms) become roomettes, as do the bedrooms. The result is 28 roomettes in the car. The H-room becomes 2 bathrooms (so the car retains the original number of bathrooms). The rooms can be reserved in total, or can be shared with a stranger. They do not include meals, and come at a lower price. 45 such cars will be needed.
1) 35 Deluxe Sleeper Lounges,
2) 45 Slumbercoaches.
Order total:
I've added a few additional cars to the overall total.
1) 15 Bag/dorm/sleeper
2) 35 Sleepers
3) 30 Diners
4) 10 Sightseers
5) 85 Coaches
5) 35 Deluxe Sleeper Lounges,
7) 45 Slumbercoaches.
Total: 255 cars: 130 sleeper cars, 85 coaches, 40 food service cars.
