The 4D was custom built for Melbourne many spec's match Comeng trains, so
the 4D could MU with them.  Original intention was for the 4D to run with
a Comeng during peak hour, and by itself during off peak.
Modifications were made when DOO was introduced, and this (somehow) made
the 4D no longer compatible to MU with Comeng trains.

Has lengths of indivdual cars and 7 car sets.
A 3 car Comeng and the 4 car 4D coupled together is 149.6 metres long,
most Melbourne platforms are 160 metres.
