Well done Daodao, nailed it in one

I'd love a turn - Any takers?

Yes they are.... Interesting to see how they (being non-drivers) would react when driving an express through a station and seeing flashes of red in their peripheral vision......

Johnston (South Wales Railway)

Seconded! Very well said.

Thanks everyone who answered.

With that quite significant deviation between the lines, is any difference between the chainages on the adjacent lines, and how do they deal with that?

Purely out of curiosity, are there any records as to the reason why this configuration was selected?

I had exactly that problem on a TPWS OSS design project a couple of years ago. The new DMU had far superior braking curve compared to the loco hauled stock also utilised. If we set speed for the DMU, the LHS overran substantially at line speed, if we set for the LHS then the DMU would either...

Ive been involved in a few different methods of logging. #1 Most computer based train control systems will record both the actions of the signaller and the inputs from the field equipment as it displays these on the signallers screen. That way, for example if there is contention re a SPAD for...

Strikingly similar occurrence in Queensland a few years ago https://www.atsb.gov.au/publications/investigation_reports/2018/rair/ro-2018-020/

Bearing in mind that the geometry of the points can be skewed by the lens of the camera, figure 8 and figure 9 in the report would seem to indicate that the crossover from the up to the down isn't particularly tight. Is it possible that the 'lurch' the driver felt was only slight enough to...

And also to bear in mind. Most possessions are months (if not years) in the planning. Any change in methodology now would not change any current planned works, and would only come to fruition next year at the earliest when travel may be well on the return to pre-covid levels anyway.

Is it just me, or does the 800 class seem to be involved in more mishaps than the HST? Or are they just widely reported than in earlier times?

Or used for rescue purposes, instead of having to erect an A Frame. It may be a deep pit that requires regular access, and then the worker involved will wear a harness and tether so that they can be recovered f they become incapacitated in anyway.

I note that some previous posters have suggested that the driver should have started braking at SY29R. Is this a 4 aspect or 3 aspect signalled area? Given the identification of SY29R as a repeater, is it there to simply provide advance warning of the state of SY29, and the braking distance...

With the correct placement of lever weights, crank throws and channel rodding quite long runs can be achieved. My last project involved a three lever frame throwing two ends of a crossover at the same time. However.... The rodding and throws were designed by a competent mechanical signalling...

How was the train driver informed? (Presuming that he / she wouldn't have felt anything) Passcomm activated or train crew called the cab perhaps?

Thats just brought back a memory! Well done both....

From recollection points will sit out of correspondence until the detection is obtained. While the route can be called, I don't think the points will motor unless detected in Normal or Reverse. And to add - I was also under the impression that at least the track circuit over the points would...
