Canberra Metro / Re: Tram Discussion
Last post by triumph - Yesterday at 11:38:30 pm
Some time ago I remarked on the variable 'thrumming' noise coming from underneath various light rail vehicles as they travel along the track. Was this rail roughness or problems with wheels?

Have now come to conclusion that the wheels are the source and that the principle cause is various imperfections ('flat' spots) distributed both circumferentially and transversely on wheels. The random transverse distribution would tend to explain why the 'thrum' is partially inconsistent.

If, in fact, the wheels have developed minor imperfections, then the cause is most likely minor skids/slips during severe braking related to acceptance testing and/or performance validation, and to extensive driver training. The only solution, if imperfections as described are
present, is the wheel lathe.

Note: Approaching Eloura St there was a horn blast and very severe brake application to a full stop. After easing forward into Eloura St Station, the driver came back through the vehicle to check that the 'emergency braking' had not caused any injuries. The stop was that severe. Fortunately, no one had fallen or come off a seat. I didn't see what the problem was, but from the stopped position, I would speculate that a pedestrian had obliviously walked in front.

Quote from: triumph on July 16, 2019, 10:37:43 pmWell, well, well. Whilst it is widely believed that the 'R' of the R series routes stand for 'Rapid' as in a quicker trip. This is not the case with TC's torturous use of plain english.

Quoting from Team Leader, Customer Experience, Transport Canberra:
The Rapid 6 route refers to the frequency of the service, not the length of time the route takes, the Rapid routes are designed to move residents across the City connecting between town centres.

So, it seems Rapid in TC speak means more often, not quicker.

Make of this what you will.
That's what I always understood it to mean, Rapid meaning frequent, it was never about the route length.

Yes, those are so horribly painful to sit up the front and hear.
Always found it strange how a few Gas Scanias had their button tones switched though, well glad they never did it 343 :D.

Yeah, TC's word for quicker routes is 'streamlined' aka all networks since 2006, but mostly network 2012 or 2014 (whichever one had that massive A3 proposal pamphlet).

Sure, the R6 is rapid, but I've seen how terrible the connections for it are in afternoon peak - Woden bound. There are some shifts that get caught in traffic before even starting at City West and some that get overloaded with passengers before hitting Kingston. On one occasion on arrival to Narrabundah I was on an R6 which was following a R6 which was at least 30 minutes late (if not more) with the one I was on being 15 minutes late cause he got to City West from his previous run that late. When I got off at the college, another R6 which was barely on time arrived too.
I've read those statistics of 'on-time-ness', and from what I've experienced, I find them hard to believe.

my ass...

The Tuggeranong to Woden corridors' R4 is supposedly rapid too, and certainly is to an extent. Between 10am and 3pm, those 10 minute periods feel like 20 minutes, and I could swear travelling from Tuggeranong to Belconnen didn't use to take as long as it does now. #bringback705 (without the cooleman extension and half hourly all day everyday)

Several points for contemplation.

Passenger loadings to determine availability and frequency is not the point. The issue is that the service is there when it is needed, so that public transport in lieu of relying on car ownership becomes a real option.

If loadings were to be the determining factor, then it is far too soon to draw conclusions. It will take years for people to come to recognise and rely on a frequent, reliable service. Meanwhile it is essential for success of the current network philosophy and its long term future to stick to it and tough it out. (This does not preclude improvements, but wholesale changes can only damage the philosophical objective.)

It might be noted that the influential PTCBR envisions a model comprising Light Rail Radials and R type orbital buses, with supporting local services.

A Canadian town faced with the cost of introducing a 3 route bus service decided to go with a supposed cheaper subsidised Uber alternative. In essence this was a heavily subsidised taxi service, where customers paid normal public transport level fares. The inevitable outcome was ever increasing popularity, with the subsidy cost soon passing the budget estimate, and now well past the high bus route cost the Uber idea was meant to avoid. Other negative issues included effect on traffic congestion.

(Oi, oi, lay off the R3, thats the one I rely on and use most often.)

The duplication has been open for at least a month now and back to 80km/hr for a couple of weeks. Traffic still builds up at the evening peak at the traffic lights. This causes bumper to bumper traffic from Majura Winery to the lights but the traffic still flows. Horse park dr flows well now both ways.

I assume that there is a fair amount of fat built into some of these runs. The 18 in particular has had low use from what I've seen. So that 10 mins can be made up pretty easily.
