Even allowing a generous spare allocation of 18 coaches and allowing for the 10 Alstom units you can have an entire 6 coach operation, but since you can't currently couple a LHB 2 car to a Japanese set you can't get the maximum capacity option.

Best case assuming everything couples to everything
4 8 coach
15 6 coach
1 4 coach (this is the morning Dun Laoghaire extra with a DART 5 minutes either side)

If you cut the journey time by 5 minutes end to end you need 1 fewer set and works for the current fleet with no engineering required
7 8 coach
11 6 coach
1 4 coach (this is the morning Dun Laoghaire extra with a DART 5 minutes either side)

What you will actually get is
6 8 coach
11 6 coach (only LHB units can run in 6 car formation)
3 4 coach (this is the morning Dun Laoghaire extra with a DART 5 minutes either side)
