Okay, I've sent along a suggestion to GO Transit/Metrolinx.... To see if they could figure out how to operationally pull it off.
My idea is:
Stopping a few "guest" Niagara Summer Seasonals at Hamilton West Harbour GO station even without it being a "through station" yet. (and backed-out of the spur to continue journey?)
Friday night's Niagara summer seasonal might be the lowest-risk train to do this economically:
(A) It becomes an extra bonus evening commuter train for Toronto->Hamilton/Niagara
(B) It coincides with the monthly Arts crawl on James Street North (2nd Friday evening of every month)
(C) It provides an extra option for university students in all 3 cities.
(D) It starts to begin to market the Niagara market to Hamiltonians in prep for upcoming (2019?) full inclusion in seasonal service
(E) West Harbour GO is open Friday evening, due to existing West Harbour trains.
Operational idea to keep delay to perhaps only 3 minutes(?) despite West Harbour being a spur:
-- Reversing the train & then resuming journey could be tricky but I make these observations:
-- I've seen GO trains reverse directions in less than 30 seconds (e.g. to correct alignment on a platform) as long as drivers were already in both ends of the train at the same time, so it seems practical if Niagara trains are already being operated with 2 driver crew in cabs.
-- I notice often 2 train crew are in the cabs, there could be 1 person at both ends.
-- To allow backing-out the train quickly from the spur, and then resume journey to Niagara Falls (and vice versa for the Niagara-Toronto trip).
-- After passing west of Aldershot, 1 of 2 train crew could start walking to opposite end of the train through the hallway between coaches while train is in motion (enroute between Aldershot and West Harbour), as only 1 driver is required to be in the cab at a time
-- That puts a 2nd train driver near opposite end of the train almost immediately upon arrival at West Harbour, making it quicker to turn-around the train, for back-out of West Harbour spur. (Even if they have to wait at the last coach before locomotive, until the train is stopped)
-- Due to its status as an excursion train, the 6-coach train is short & rarely full on Fridays after passing Burlington, so there's plenty of room to walk from one end of the train to the other during the Aldershot segment.
Benefits:
- Builds ridership incrementally for Niagara summer seasonal towards future Niagara extension
- Hamilton's population is somewhat antsy about Hamilton LRT. They'd like to see some movement in incremental Metrolinx service improvements. Doing this could provide good karma for election 2018
- This gives you an excuse to announce the opening of the parking garage at West Harbour GO station (by having successfully found a way to expand West Harbour GO service quicker)
- The Niagara service could also go hand-in-hand with a pre-announcement of an incremental service expansion of other kind (e.g. 1 or 2 more other trains per day)
This idea is:
What if GO can stop at least a few of the Niagara seasonal trains in Hamilton -- even before West Harbour GO is a through track?
