I am going to make a guess here so please allow me to take a stab at this. Taking a NYP comparable bilevel car like those mentioned above and putting in Delta One Mini-Suites (which are really just Off-The-Shelf modules made by Thompson Aero | Intelligent Design
) I will make the following assumptions:
85' long car.
50' clear floor space on each level (between trucks).
17.5' floor space mezzanine end level over each truck.
6' foot long beds in each room and suite.
18" space gap between lay-flat beds for passage (this is in front of each seat).
This would give you approximately 7.5' per mini-suite unit.
50' divided by 7.5' would give you approximately 6.5 units per row (since they are staggered that half unit may come into play like at the end for stairways).
You can fit in approximately 8 rows per car (four across X two floors).
Which would give you approximately 48 min-suites in the mid-section. Lets give one to the attendant so say 47 pax. You are probably going to lose one or two for stairways too so lets say 45.
On one 17.5' end you could have one vestibule (3'), walkway with ADA room bathroom extension on one side (2'), an ADA room (7') and 5.5" dead space for miscellaneous mechanicals and/or coffee maker and/or stairs/hallways, etc.
On the other 17.5' end you would have room for four 6.6' modules plus 3' of dead space. So that could be four more "double roomettes" but probably more likely two "double roomettes", one double bathroom module (i.e. two restrooms), and one shower. The 3' of dead space on each side of the aisle can be used for some mechanicals and/or storage and/or coffee maker, and/or stairs, etc.
So a grand total of maybe:
46 single mini-suits - 45 pax + 1 addendant
1 ADA room - 2 pax
2 Double Roomettes - 4 pax
Grand total of maybe 51 pax + 1 addendant.
This is maxing it out of course. With more detailed dimensions we could see how the need for short stairways and walkways and room for mechanicals and storage would work. But this is just a quick try at looking at the potential new type of sleeper on a long holiday weekend.
Need to get a detailed schematic of a NYP bilevel car and a life!
Merry Christmas all!
