Posted in the other thread, but the commute back from the Abbotsford Canucks game was brutal, took nearly an hour to even leave the arena area.
I'd say McCallum Road makes sense as an Abbotsford station (and terminus of Phase 1). A station at Mt Lehman Road would make sense, and have bus service from this station through Aldergrove and connect with Langley Centre Skytrain station. After that nothing in Langley really justifies a station until Calvorth Exchange. Then either a Terminus in Surrey Central or Lougheed Town Centre with a station somewhere in Guildford along the way. Lougheed would give an option for an eventual extension into Vancouver, but Surrey would keep costs lower.
Overall the
Mountain Valley Express plans make the most sense, but that tunnel from Surrey Central to Lougheed would be expensive. Perhaps get Surrey to Abbotsford running as a cheap phase 1 first, we could actually do that about as fast as we can do this highway expansion (and the train could probably be cheaper too if we just went with a small fleet of DMUs and fairly simple stations).
