For the record:
Hitachi Trains:
Motor Car: 23.6m long, 86 seats.
Trailer Car: 23.6m long, 96 seats
Trailer Car (formally 'D' type car): 23.6m long, 89 seats.
6 car Hitachi (M-T-M-M-T-M): 536 seats, 1520 crush capacity.
(less seats if there is one or two former 'D' cars, 15M did have a
testing area, but this is now normal seating)

Comeng Trains:
Motor Car: 24.0m long, 92 seats
Trailer Car:, 23.2m long, 102 seats
6 car Comeng: 572 seats, 1392 crush capacity.

4D train:
Motor Car (non-driving): 19.4m long, 97 seats.
Trailer Car (driving): 19.6m long, 78 seats.
4 car 4D (equivalent of 3 car comeng): 350 seats, 976 crush capacity.


Summary:
Train:		Seats:	Crush:
6 car comeng	572	1392
6 car hitachi	536	1520
8 car 4D	700	1952

All of similar length.

The Zs have very few seats in them by the time the conductor stand was
removed and not replaced with anything, and the Metcard machine took
away 4 more seats.
