Re title, their are no 4 car intercity trains, intercity trains now are the XPTs, and some Xplorer services. The state government incorrectly call the V-sets, intercities, but we won't go there at the moment.
That is highly likely to be an Outer Suburban Oscar (H set) if it terminates at Wyong (& yes some H-sets start from Blacktown for example, then "terminate" at Gosford or Wyong, and then "start" another trip to Newcastle), not an interurban
I can understand peopel using interurban trains between Central & Hornsby, as 99% of the time, their is no direct suburban train between Strathfield & Hornsby, but that is the problem, the interurban trains are being used as "suburban" services between Epping/Eastwood/Strathfield & Central. The stop at Eastwood was only added as a political stop, this stop should be scrapped from interurban runs, and if interurbans need to stop at Epping, Epping & Strathfield should be set down only (d) to Central, and pick up only from Central (u).
Haven't got time to look, but I think with some exceptions, most are scheduled as 8 car V-sets.
AndyV, a copy & paste is all you're going to get from the "Aunt Gladys & Co" clan.
You're very express alright, so quick you seem to be missing most if not all the pertinent details from the OP's post...
Raichase pretty much nailed it, but I'll add a little...
You'd better tell ALL the NSW Trains crews about this "no 4 car intercity trains", cos I'm fairly sure most of Sydney Intercity, Newcastle, Gosford, Lithgow and Mount Vic depots are under the belief that they operate "intercity trains", whether they be 4 or 8 car sets...
And do please clarify for us, when OSCars are tabled to operate services from Sydney to Newcastle (last time I checked, both locations were cities), despite being a train designed and meant for "outer suburban" use is it not being used as an "intercity" service and thus an intercity train? "Haven't got time to look, but I think with some exceptions, most are scheduled as 8 car V-sets."
- perhaps you SHOULD look... If by "some exceptions" you mean A LOT of exceptions, then you are correct. Otherwise you are talking out of somewhere not your mouth...
Sydney destined services during the morning peak, are nearly all 8 car services (04:29 from Newc until the 07:29), however after the morning peak finishes, they are alternate between all 4 car sets for the all stations, and 8 car sets for the limited stops services - Often with the Express being a V Set, and the All Stations being an OSCar.
In the other direction heading North, after the first train out of Sydney at 0345, the rest are 4 car sets until 0745, when they are 8 cars until 0845 when they return to 4 cars until 1415. The Afternoon peak in both directions is similar again.
Suffice to say, AndyV is quite correct, and quite justified to be annoyed and the poor tabling of services and sets. He is also quite right to suggest that anyone else who is also adversely affected by the inadequate allocation of sets for tabled service, make complaints to the relevant entity. Despite a form letter response, you can be sure that the numbers of complaints are noted and counted.
If there are petty little twerps counting the number complaints recieved about "not enough announcements", "Too many anouncements", "Announcements too loud", train didn't stop long enough etc, you can be sure they are also counting how many complaints are received about overcrowding. Some of these decisions maybe political, in which case, make the most of it, and make noise so you are heard and hopefully make a difference.
If you are content to say nothing, resigned to the fact that your voice won't do anything, then you deserve all the lousy service you get. Considering I've seen a train taken out of service within hours of receiving a complaint on 131500 about graffiti in a carriage, police sent to meet a train after a 131500 complaint (crew weren't informed until after), thus I do believe the system can work if some know how to use and make the most of it.
