Absolutely. I think it is a shame that better use is not made of the
West London line as a third major north-south route.

Are the existing trains on the WLL crowded enough to warrant more?

The Thameslink Line is little used as a through route. I can't remember the
exact percentage quoted in the TL2000 inquiry, but something like 95-97% of
TL journeys start or end in Zone 1. TL2k won't change that. The point of TL
and TL2k is giving people from north and south access to numerous stations
across the central area - giving the north access to the south is a largely
unused side-effect. The WLL doesn't have major employment or entertainment
centres on it (apart from Westfield on a Saturday), so will never have the
demand of Thameslink.
