Given that there are restrictions on single deck cars in the curved
tunnels at Jolimont, could it be a similar story for the 4D around the
curves in the Melbourne underground?  Yes, a Comeng and country car can
get around the loop safely, but if the (higher) 4D cars were normal
length, their centre-overhang may see their higher bodies touch the
tunnels.  Keeping them shorter may have been the only way to achieve
safe clearance.

If the cars were normal length, go for 3 car sets rather than 4, hence
alleviating the problem of shorter platforms.

Cheers,
Craig.
