Here is a question for the (far) more knowledgeable folks than me....does a move to shorter trains travelling more frequently open up the opportunity to fit in that dream of mine of a Liberty Village stop on the KW GO line? Previously it was explained to me that the combination/proximity of the curve and the slope into the Strachan underpass made it very difficult to fit in a station platform anywhere in the area for 10 or 12 car trains.
Adding in the Liberty Village area with its proximity to the Exhibition/Ricoh/BMO would seem to be an excellent driver of, particularly, off peak travel......and, to this laymen, this could be an interesting by-product of going to shorter more frequent trains.
There will never be a station south of Dundas to service all the lines. Using 3-5 car trains, you can only put a station on each side of the corridor that is very narrow even buying land for a station. No parking and only walk-in and there should be more of them.
The east side service the Barrie line and the west side the Milton line. To get the other lines to service those station will require a lot of crossover moves and becomes an operation nightmare once service start to fall under 30 minutes, but most of all,"PEAK TIME". If a switch fails, it will end up screwing up the whole system.
You can put a station on the Milton Line south of Queen and one at King for the west side.
The east side will be south of King as well at Queen.
You can put in a station for Dundas and require buying the land in between the Barrie and the KW line that will service both lines. Don't know of a spot for the Milton Line without doing some major impact on the area.
The corridor is not wide enough to spread the tracks apart for platform with the 8 tracks going in this area. You could if there was less tracks, but not the case today.
I have call for more stations to be built on all the lines with most of them being for walk-in and using shorter trains all day long. Metrolinx/GO Transit need to think local as well long distance for service to the point you run different types of service to service these new station. I see the milk run that service all the stations including the new ones. Hip Hop that bypass various stations; short runs that only operate between various point only; Local Express that runs from one or 2 stations to Union; current service; Mid express running to/from X station to Union and then the long express that make very few stops from Union to end of line along the line what is there now.
GO should be running 5 car trains off peaks for most of its life, but the cost to break/makeup a train today is too expensive. If DUM/EMU built to EU standard were to be use in place of current standards, the cost to doing the break/makeup becomes a non factor to the point you could run various length of trains at the same time for peak service.
