Previously I have put forward the idea that MOOSE would require approximately a three-fold increase in trainsets from the 6 identified in their CTA submission in order to meet its desired scheduling of hourly service. (

Currently MOOSE is planning for trainsets with three coaches, capable of transporting just under 500 passengers per train (480 seats). With trains leaving from the six different terminus along the various lines, that means that the network as a whole has a capability to move approximately 3,000 passengers per hour.
MOOSE has also indicated that they expect to transport approximately 30,000 passengers per day on return trips (equal to taking 25,000 cars off the road). In order to move those 30,000 passengers, it would take 10 hourly cycles in order to move those passengers in one direction and another 10 hourly cycles to transport them back. This in itself is mathematically possible if you provide hourly service all day, however passengers don't tend to spread themselves equally throughout the day. Rather, the bulk of the passengers would tend to congregate in the peak hours in the morning and late afternoon.
For arguments sake, let's assume that 80% of all passengers will travel in peak periods and that the peak period can be covered over 4 hourly cycles. 80% of 30,000 comes out to 24,000 passengers during the peak period, and divide that by 4 hourly cycles would equate to 6,000 passengers per cycle. Since there are six different trains in each cycle (one from each terminus), that would mean that each train would need to transport 1,000 passengers and would require a minimum of 6 cars. Once again, that's an absolute best case scenario where passengers are evenly distributed along all lines and in each hour.
This doubling of coaches would obviously significantly increase capital expenditure costs as well as operating costs. It would also have other implications such as in regards to station design.
An alternative to longer trains would be more frequent service. A 30 minute frequency with 3 car trainsets would accomplish the same task, but would be more expensive as it would also require a doubling of locomotives and additional crews.
Most of my figures come from MOOSE's letter to CTA dated 25 Nov 2016, page 6 as follows:
"(a) Frequency of the service Moose will provide train service to stations approximately
every hour from 5:30 am to midnight. The practical constraints of each line remain to be negotiated with other railway operators.
(b) Expected passenger loads Each train will consist of three bi-level coaches, for a total seated
capacity of 480 per train. It is expected that the entire system will carry more than
30,000 passengers per day."
