Well, yes. If someone wanted to go to all that trouble, they might as well just put in a tramway.
Why even talk about trams and Obahns down Port Rd when we have a perfectly good but under-utilised rail line ...it just needs to be electrified with some minor stops removed, and some more modern station facilities.
Trams and Obahn are slowed down by intersections, the rail line is not.
For heavy rail to work, it needs at the extreme at least 2km between stops. Under that distance, light rail is cheaper, quicker and more flexible. So, unless enough stops are removed to make station distances 2km or, preferably more, trams and O Bahns make sense. So far, so good. No disagreement.
The problem comes when the stations get shut down. Howls of outrage mean the stations are reopened, and we are back to square one.
At the moment, the Port and Grange lines run with tram stop spacings mostly, but with slower heavy rail costs. Heavier equipment, slower acceleration, signalling that is required for heavy rail operation, but not needed for trams makes it grossly uneconomic. Electrification won't solve any of that. In fact, the economics are so bad, no economist would ever recommend throwing more money at it.
The best would be elimination of all stations with less than 2km spacing.
If that can't happen, the next best is a tramway or O-Bahn.
Sounds good in principle, but when you start to look at the logistics of closing stations things get a little complicated.
For example, applying your 2km rule to the OH line would see Bowden retained (rightly so, given that it is brand new and serves a TOD) but Croydon closed in favour of West Croydon. But both of these stations serve retail strips – Croydon’s being significantly busier than West Croydon’s. So do you close a brand new station which serves a busy retail strip, or keep that one and close the other?
Either way, both are closer than 2km to Kilkenny so that would have to go – but, when the debacle over the old Bianco’s concrete works is resolved that leaves a sizable chunk of land a few km from the CBD which would be perfect for a mini TOD (especially if and when the adjacent O-I glass bottle factory and John Shearer factory eventually sell up their sites for development, which I would be surprised if they didn't within the next 10-20 years or so) – losing that station would make any development of these sites far less attractive and I would imagine that Charles Sturt would be very keen to retain it for this reason.
If you do keep Kilkenny for its TOD potential then Woodville Station is only 1.5km away but that not only serves a main road with medium density development potential as well as Woodville High School, the Civic Centre, retail strip etc but is also an interchange station for the Grange line.
St Clair is only 1km from Woodville but that services the new housing development, of which the station formed a significant part of the masterplan (and is one of the few stations which genuinely does service a shopping centre and supermarket).
Cheltenham is only 600m from St Clair but that station services the Port Adelaide football ground which would be a blow for SANFL games and for the development plans Port Adelaide have for this site.
Alberton is the first station along the line that I can't see an immediate argument for keeping but I know very little of its patronage, the local area etc.
