A new TransLink FOI release has revealed the expected capital costs for the Surrey-Langley line built as an at-grade LRT or as an extension of SkyTrain (Expo Line: Langley Extension).

TransLink changed its tune this week and released a report to theBreaker under the freedom of information law that includes separate estimates for an LRT line and SkyTrain line to connect Surrey and Langley.

So some summaries since you are all interested:
The LRT option is now estimated to cost $1.95 billion in 2022 dollars, plus several additional unlisted costs. This will include
13km of grade-running track and 3 km of elevated track, including full elevation through the Serpentine Valley, which was determined necessary due to poor soil conditions. The LRT option assumes the use of 19 40-metre long light rail vehicles.
The station platforms will be 40m long; as well, the LRT estimate only includes canopy covering for half (20m) of the platform, and there is no indication of whether platforms can be expanded beyond 40m. Numerous additional costs are not listed, including: physical barriers at LRT street crossings; park and ride facilities; bus loops (other than basic street facilities); work to the existing Serpentine River Bridge; operating costs; and GST. With these costs included, LRT on the Surrey-Langley Line will tally in at over $2 billion.
The SkyTrain option is also expected to be delivered at an increased cost, which totals $2.9 billion in 2022 dollars, plus some unlisted costs. The increased cost seems reflective of the much higher ridership that a SkyTrain extension will see. This amount buys almost
16km of fully-elevated track built to the same standard as the existing Expo Line, and includes costs to enable seamless integration with existing SkyTrain (such as updating of next-train displays on all existing Expo Line stations). The
stations will have 82.5m long platforms, fully canopied, mostly located on the side of Fraser Highway, and with an allowance of 12 bike lockers per station. The cost estimate includes the acquisition of 11 5-car Mark III trains (55 cars in total), and an allowance is included for a small vehicle storage facility. The cost also incorporates all Fraser Highway roadwork (widening, replacing of median, replacement of 644 street lights), which is usually borne by the municipality, i.e. during previous SkyTrain expansion projects.
Both alternatives adopt the same 8 station locations (the LRT alternative includes a 9th station at King George Blvd beside the SkyTrain station) and include a generous 25% contingency allowance on all items, on top of a 20% contingency on property. It should also be noted that the estimates are in year of expenditure
(2022 dollars) which accounts for why they seem absurdly high. In more recent dollars (2016 dollars), the report estimates Expo: Langley at $2.45 billion.
If we compare to the 2012 SRTAA estimate ($1.8 billion in 2010 dollars) and discount the generous 25% contingency which was not in the 2012 estimate, the cost for Expo: Langley has actually been reduced by about 8%.
These are cost numbers only and there are
NO numbers on expected travel times, ridership, fare revenue and fare recovery.
However, a strong hint on the operating speed difference is the amount of trains deemed necessary for each option. The LRT option specifies a need for 19 light rail vehicles; the SkyTrain option requires 11 5-car trains. Increasing the operating speed reduces the amount of vehicles necessary to operate along the same distance; lower operating speed requires more vehicles, so this would suggest that the proposed SkyTrain alternative is nearly twice as fast as light rail.
