Timetables on the Grange line have always been flawed.
So many trains have been delayed on this line for close to 100 years.
Had it not been for the munitions plant and subsequent Philips factory at Hendon this line would have been long gone.
I am currently living at Grange. forty minutes by bus to city via Henley beach Road, 35 by Grange Road
20 minutes by train.
However the half hourly service compared to the 15 min bus headways mean it can be faster by bus.
It comes back to a lack of rollingstock , lack of inspiration by timetable planners, and the political stability of the seat.
Currently most down trains wait at the old Holdens station site for the up train to clear. Just like they have done for longer than I have been alive. It used to be better when Albert Park had a crossing loop.
All services stay at Grange for 13 minutes, Day and night. If this time were utilised better it would be quite easy to run services every twenty minutes.
However this would require an extra set of railcars, or need a split of a two car set to two singles, but that does not increase capacity, just frequency.
If the Gawler electrification ever proceeds ( cough ,cough, cough) the usual at least fifty percent increase in patronage on electrified lines will require an increased fleet of sparks. If the current fleet were to be cascaded to other lines there would be some capacity to increase frequency and patronage on the whole system. But that would need a group capable of planning for the future.
( it is like a group I think of, who built a very expensive hospital to cater for an ageing and expanding population with just sixty extra beds and an emergency department that is already overcrowded)
I also remember discussions with my late father about his first job. It was in the city and he lived at Cheltenham.
The train was a maximum seven car consist, Hauled by an F class, always crowded as were the trains either side of it at about fifteen minute intervals. There was a push from locals to their local MP's to add another service.
This would have required a new loco and seven new carriages ( possibly built by Pengilly/ Holdens) and some extra train crew.
In preparation for this the existing train was run ten minutes later, to clear a path for the extra service.
The initial result was that people arrived in the city too late to start work, so they were forced to walk to Torrens or Port road to use alternative services.
As a result patronage on the train dropped so only 4 cars were needed and the railways saved the cost of a new consist.
65 years later I moved into the same house, had a job at Marion and was forced to use public transport.
Left for work at the same time.
It had progressed from an F with 7 cars ( about 400 seats)
to a 2 car redhen with ( 200 seats) previously had been a 3 car redhen.
Today it is a 2x 3000 class, still about 200 seats.
We have St Clair, urban infill and TOD's all along the way, roads that are choking with poorly sequenced traffic lights, and less people walking or riding bikes to work. And how much has the public transport been increased?
In the days of Holdens at Woodville it got busy around the area for twenty minutes or so either side of shift changes.
Nowadays to travel along Port Road from Woodville south to Albert Park can take you 25 minutes because of poor traffic light sequencing, level crossing delays, and complete lack of interest by people in improving traffic flows.
This is very close to where the outgoing Premier allegedly lives. And just up the road from where the former transport ministers electorate is.
What hope does the rest of the state have?
Or alternatively travel via Torrens Road, past the skinny carpark alongside Arndale. Yes Torrens Road is a skinny carpark several kilometres long, ( or travel on David terrace and take five sequences to clear one set of traffic lights, and two or three trains to clear the level crossing. )
Then try to get past the 40 year old railway overpass ( HA HA HA HA) with previously acquired houses now scrubby park) and incomplete bike lanes.
All this to get to the city of Adelaide, You know the 20 minute city.
Sorry for the long post, but this state really needs a new vision to cater for public and private transport into the future
