Are the Western expresses not crowded enough?
well doesn't that play nicely with your 10 car k set theory?
Yes, I ran the numbers and it's 12m too long
Too long for what?
The idea I came up with was to run a 2K into Sydney Terminal before peak, then pull off an inbound Western 8K into the same bay platform, and amalgamate. This creates a 10K that can be run out of Sydney Terminal as a Western Express. However, it's 12m longer than an 8V so I'm no longer confident it can fit where it has to.
Prior to the V sets, they used to regularly run 10 car U boats (same length as the Vs IIRC). Also, they used to run 10 car V sets on some runs too. THe main stations (at least) on the west can handle 10 car V sets, as can (at least) platforms 1-10 at Central. They could handle 12 car suburban sets.
