josh04 posted:"activating an automatic derailment"? The theory is that instead of allowing a train to go through a red signal and into the path of another train, you stop it safely by dumping it off the track before it conflicts with anything else. Particularly with runaways; when they were first installed most goods wagons had only hand brakes and might occasionally go for a wander of their own accord. It's neater if you've got the space to build effectively an extra siding to send it down instead of just dumping it in the ballast, but both work.

Presumably derailing fucks the track up a bit. And in this case the overhead line pylon. I thought the class 165 would be able to stop if it passed a red though without having to derail?

I suspect the overhead pylon wasn't there when the track layout was designed. My understanding is that you can have smaller overlaps and signals closer to junctions if anything that passes the signal cannot intersect other traffic.

Incorrect. You only need trap points to protect against vehicles running away when stabled for a length of time. The line is a siding, used to be used for stabling locos back in the day. If you want a shorter overlap you use a reduced (based on speed) overlap or a restricted overlap (protected by approach releasing the signal in rear).

Particularly with runaways; when they were first installed most goods wagons had only hand brakes and might occasionally go for a wander of their own accord. Very rarely do you have a set of mainline catch points. The cases that I'm aware that they are installed are for run backs on steep hills (Outside Gloucester for instance). More often than not, sidings will have catch points just beyond either exit signal to prevent run-away wagons or trains. Interlocking and line separation are the primary forms of mainline defence; with the addition of AWS and TWS to onboard systems to further prevent it happening.

As a matter of interest, is there a reason the Great West line seems to slow to a walking pace once it's into Somerset? It seems weird that Brunel's line is good enough for 125mph for two thirds of its length and suddenly turns into a scenic railway. (Yes I know technically Brunel only surveyed the line personally as far as Bristol but he was still involved long enough to do the Albert Bridge and piss about with vacuum cleaners at Dawlish)

Since I've moved to Brussels I've grown to dislike touch screen ticket machines - the ones for the metro/tram/bus here were installed before them and have a big dial to control what you want and big buttons to go forward and back. I mean they're a bit slow (although cards process quicker here for some reason) but there's a lot less dicking around because the screen isn't calibrated properly or because it's broken. Basically modern technology manages to somehow be worse in every way for ticket machines

So many ticket machines are garbage. Why can't you buy more than one ticket at once when using a 16-25 railcard? Why don't all the machines at Victoria sell tickets for the Beckenham line (and most why do they silently reject your card instead of telling you they can't?) why are they all so slow? Why are there 50 different tickets to Brighton from London Bridge, and no departure boards near the machines leaving you to guess what the correct one is. So many questions

Instead of making you explore the various paths through the ticket and railcard options they should make you say what journey you want, what cards you have, then display all the options(with live train times!) so you can pick one.

Belgium railways are poo poo but they do some cool things that I like - one of them is that on the newer trains they have LCD info screens that display live departure info for the next station just before you are going to arrive, which I imagine would be pretty handy. It's also funny because it also changes languages when you cross the internal borders - Dutch in Flanders, French in Wallonia and alternating between the two in Brussels.

My TOC has recently changed from PDA based Avantix ticket machines for retail staff to Star Mobile smartphone based platform. Somehow it's worse than tech over a decade old, seemingly faulty by design to circumvent conductor's commission (coupled with the fact a lot of TOC's are enforcing condition 6 and also booking offices still issue traditional tickets whilst on board tickets now use half the rainforest). Locally our depot is taking a beating too, the local paper is leading a witch hunt against any cancellations: the company blames staff shortages but won't recruit anymore staff, so the staff who do turn up like myself just get all the grief about the absentees. Even though it would kill off the salary progression I'd take BR Mark 2 in a heartbeat right now.

Unions balloting guards and drivers for strike on Northern and Merseyrail franchises ahead of what the RMT has called 'a spring and summer of discontent' regarding Driver Only Operation (DOO for short, rebranded as DCO to confuse issues). With regards to the Northern franchise implementation of DOO, apparently it was estimated prior to the franchise commencement that it would take 12 days of strike action to break the unions. Guess we're going to find out.

OwlFancier posted:If Northern get rid of their conductors then nobody is going to bother buying tickets... Half the platforms are unmanned and have no ticket barriers. This is true though even on rural lines the plan is to implement more barriers by the end of this year now that the franchise has become more revenue dependent. They will still likely have revenue protection going out on trains but only at peak times and with no safety training. The subsidy reduction/revenue dependence is one of the reasons you may have noticed Duo tickets were phased out in September, replaced with off peak fares. This is because they're now pushing the enforcement of condition 6 aka buy before you board where possible so they can financially penalise passengers who don't.

Bozza's a signalling engineer. Politely, they're like the witch doctors in the railway engineering tribe. They traffic in a world that touches only lightly on our own, concerning themselves with the rites of flank protection and the proper ways to appease the sighting committee. Something as mundane as a collapsing wall wouldn't even register. What you've got here is a typical railway geotechnical engineering headache. It's a Victorian era earthwork which was almost certainly designed using the "suck it and see" approach because more advanced methods didn't exist then. Typically they have a terrifyingly low factor of safety and the railway network is littered with these timebombs, just waiting for an extremal rainfall event to flop over. Dawlish, Farnham and that one in the Midlands where the tunnel mouth came down last year are all recent examples. This one is compounded because it's likely that the railway land doesn't extend beyond the cutting. Network Rail have no right of access to the land adjacent or right to control what gets put on it. You can see from the aerial picture that the slope failure plane extends back probably five metres from the cutting so anything closer than that- portakabins or fridge mountains for example, is going to add load to the cutting walls. Some poor bastard is going to spend the next five years of week nights between about 0200 and 0530 (when the electrified wires can be isolated because the trains aren't running) spidering over every single square foot of these walls trying to work out how the hell to tell if they're going to fall down before said poor bastard is retired and safely out of blame's way.
