I have a few questions about the Sydney Trains and NSW Trainlink networks:
- Do all stations in suburban Sydney minus the Carlingford Line have Platform Information Displays (PIDs)? I am yet to find a station without them.
- Why did a station with low patronage like Casula get lifts before a highly patronised station? likewise, why is another lowly patronised station like Adamstown getting lifts? The lifts at these stations came / are coming with new footbridges, is there a plan to eventually put a lift at every station (including intercity)? and the new footbridges gave them the opportunity to get those stations over and done with? or do modern disability laws require the lifts? but then why did another lowly patronised station like Clyde (which is actually an interchange so would probably warrant lifts more than Casula and Adamstown) only get stair lifts?
- Why terminate trains at Penrith and Campbelltown when Emu Plains and Macarthur are one station away? since the train is already in the area, wouldn't it make the network more consistent to terminate all trains at Emu Plains and Macarthur? It's not like Hornsby - Berowra which three has intermediate stations, I can understand why trains terminate at Hornsby.
- Why are only Tangaras (and the occasional OSCar) used on the T4 Illawarra Line? is there not enough other rolling stock available? but then wouldn't it be best to deploy a variety on all lined rather than just having Tangaras to Sutherland and Waratahs to Richmond for, once again, consistency? although I can doing this could potentially increase maintenance costs. Also, is there any reason in particular that Tangaras don't normally operate on lines that use the City Circle? or is this just coincidental?
- Why with the current timetable and map, do we have trains terminating at Homebush but few trains serving Homebush as an intermediate station? It's crazy that Flemington is the station after Homebush, yet requires one to catch two trains to reach, good thing this is changing soon.
- Why do South Coast Line services which use Central's intercity platforms also stop at Redfern (I can understand why the services using the Eastern Suburbs Line do), it's the station after Central and these are express services that should aim to leave the city as quickly as possible. Wouldn't Sydenham be a better stop as it would allow connections with the T3 Bankstown Line?
- Why do 8 carriage trains service the T7 Olympic Park Line yet only 4 carriage trains service the T5 Cumberland Line? I'm not sure about patronage but the Cumberland Line certainly has a higher catchment than the Olympic Park Line.
1. I don't know. I think they all have at least a bare minimum display.
2. Because these decisions are made by bureaucrat's which logic doesn't make sense to them. Very long term all stations will eventually get lifts because of disablility laws.
3. Many reasons, one is track capacity. Penrith, macarthur and campbelltown have 3 platforms, with 1 side platform dedicated for terminating services. This allows the running lines to remain clear for other traffic to pass. Another reason is history, emu plains wasn't a suburban station and macarthur is a fairly new station. Another is crewing related.
4. they moved the T4 to only have tangara's to have consistency in the line but also remove tangaras from other lines. Currently the main maintenance depot for tangaras is also at mortdale. Its just the current timetable means that tangaras don't go through the city circle, there isn't a reasons for why they can't and occasionally do run through. Another reason is due to where the waratahs are maintained. It just makes more sense to run waratah's on the western, south and bankstown lines.
5. I have no reason why this is and I think it should be changed.
6. while I am unaware of what the exact reason why, possible reasons include that all South coast services are only 160m at most and all services can use redfern, this is not the case for newcastle or blue mountains services. Redfern allows interchange from all the lines going west along the main suburban line, along with limited number of BM and Newcastle services. Has always confused me why sydenham isn't a regular stop. It also allows the interchange of people wanting to go into the cbd, taking away strain off central which can get quite crowded.
7. 8 car trains on olympic park is likely just so they don't have to screw everything around when some event is on and would require an 8 car set.
