Manually reversing the wrong way 26/06/2016 at 15:51 #83227

This "manually reversing" thing is a confounded nuisance!

I reliase it's there to prevent people exploiting a reverse instruction when they want to set a signal to danger, but let's be honest - it's a very brutal and kludgy workaround.

I run a ficticious timetable on the Brighton map, and have a coal train emergin from the Hove sidings. The first train appears and must be run-around before another train is joined into a push-me-pull-you fo 300m in length. I don't know how accurate this is, it very difficult to get any information about what I've discovered to be the Didcot Sppedlink Coal Network, I just remember them briefly rolling through Worthing when I was in my teens and out far later than I ought to have been. I welcome any information any of the SimSig community can supply, but I believe it's called 6V04.

So the train (6V02) arrives at Hove, platform 1, and detaches it's locomotove. The loco (0V02) detaches perfectly fine, and sets off in a Down direction, stopping at signal 1400, as it's supposed to.

At this point 0V02 reads "Dn | Waiting for right-away at Hove West (reverse)". After a minute it begins moving but in the wrong direction, and it'll disappear off the edge of the map if I don't quickly tell it to reverse.

So, I tell it to reverse and get "Manually reversing", the enforced two-minute kludge to prevent naughty players from decieving only themselves. Besides, why exactly is it two minutes? The driver of a twelve carriage train could never make it to the opposite end in that time. But this is just a locomotive - it shouldn't take any time at all to reverse.

Anyway, eventually it does get moving, and takes it's sweet time to crawl back to the point where it should've been reversing from in the first place, and gradually makes it's way to signal 1391, where exactly the same thing happens again! It waits for right-away, and hurtles off towards Brighton. With the same consequences that it must be manually reversed, two minute wait, the the slow crawl back to the signal it just left.

I'm not sure which to report. One or the other must be a bug, perhaps both. What do you think?

The timetable isn't right.

If you try and validate 0V02 it will not validate as there is not a valid path between the two reverse points.

You need to insert "Hove" between them with the passing time box ticked.

Try that and let us know if it works or not.

"kludge(n):an ill-assorted collection of parts assembled to fulfill a particular purpose."

As it was a single requirement coded to meet a specific goal, I think we can agree you probably meant something else.

Assuming Mr. Fulcher is correct (and I have no desire to check given the accusations), perhaps you could use the tools provided for free to check the timetable before venting? If there is still a bug then of course I will attempt to fix the problem.

Actually, that did fix it for signal 1400, which is to be expected since (as you said) there's no direct route between the two.

More suprisngly, it fixed it for 1391 as well! Can't work out why, since that was always direct with nothing in between.

Anyway, Thank you very much for spotting that, it's now working as it should.

At a guess, because of the missing location the sim would not be recognising that the loco had reached 1391 so there was no reason for it to change direction.

Sorry Geoff, it wasn't meant as an accusation nor a vent. I was trying to express a problem I was experiencing in full, and intended no actual offense. I sincerely apologise if my words came across as angry (it's been said before) and is genuinely accidental.

It’s not really my place to say, as I was not part of the conversation, but as someone who often feels this way I thought I’d say that I wouldn’t worry so much about it that you end up “hating yourself”. A mistake/miscommunication was made, it was pointed out, and you apologised. Think of it as a learning experience – what not to do in the future. Don’t let frustration cloud the actual question you’re asking. Instead, ask for assistance up front, and people will help. ;)

Think more along the lines of: “I’m struggling to understand [this], can someone please help?” rather than: “This is frustrating me and I hate it.” and you’ll be fine. ;)

We’re all nice people here (really)! :)

The problem is that the "hack" was a fairly accurate simulation of reality. If a signal needs to be knocked down for whatever reason the signalman should be able to talk to the driver and then cancel the signal without getting "points off". I actually know of situations where canceling route is used as a strategy to speed trains up due to limitations in the ATC system! In less favorable circumstances the conversation is used to establish an alternative reality that won't get the signalman marked off if the signalman has in fact made a routing mistake. "Can you please reverse direction" would simply be a euphemism for "I have to take away your signal because I screwed up but I don't want my management to know".

People like yourself often have the mistaken belief that telling the driver the signal is going back is something that is perfectly acceptable and possible. It's not. If a driver has a signal go back in his face then his stopping distance has suddenly plummeted and he needs to act swiftly to be able to stop in time - if he can. Sometimes it may not be a problem; other times there may be no slack in the system. Either way, you don't try to hide behind tricks. Dispatchers I know would take an extremely dim view of your final sentence.

Mike in this country a Signaller making a mistake that required him to replace a signal, for example wrong routing, is in itself unlikely to get him in much trouble providing there isn't a pattern of him doing it too often.

If he were to cover it up, as suggested in your last statement, and the boss found out, he would probably lose his job.

The point is that you contact the driver and ask them if they can get stopped in time. Since stopping distances are wildly conservative it's usually not a problem and certainly better than waiting for the driver to stop "on sight" in the face of a mis-route. I had the opportunity to take a train's signal myself during a tower visit when the dispatcher called and told the operator to put an long distance train ahead of the local on the local's track. Operator called the train first to let them know even thought because there was an intervening station stop there wasn't any risk of a signal overrun.

I've have observed similar operations at other points and usually the dispatcher calls and asks if a train can get stopped by the such and such signal. The crews know that sometimes s*** happens. For realism SimSig should offer a "stop shot of next signal" feature and once the train has stopped (if it can stop) the signal can be taken away without penalty.

I thought you folks worked in the land of Big Labour where unionized workers looked out for eachother. With what dispatchers and crews tell me here, nothing has happened until it goes on the recording tapes. Dispatcher friend once forgot to pull up a signal and delayed a train for about 5 minutes. The crew was nice enough to entertain the suggestion on the radio that there had been a disabled passenger needing assistance at a certain station. Another time a train had gone past a place it needed to stop and the dispatcher offered up on the radio that he was in the correct place, right?

On the other hand my friend once did a favor to a freight train trying to get onto the NEC before the white period and it took longer than anticipated so my friend had to run a commuter train to another interlocking and change ends on the main line. The commuter engineer was pissed off and give my friend a slow turn which then delayed a high speed train and got my friend a letter of screw up in his file. That's what can happen when people get snippy with eachother.

Unless you've managed to foster some sort of antagonistic relationship between operating crews and signalers this sort of back scratching goes on all the time.

Some are generous; others are right on the limits. There are limits [in the UK] on the maximum spacing of 3 and 4 aspect signals, and between a repeater and a main signal.

Drivers can ignore calls from signallers if they are concentrating on something else - slowing for a station or signal, for example. So even if you wanted to call the driver, (s)he might not answer, or answer too late for it to have any effect.

Every delay of over two minutes is investigated and attributed to one cause or another. Delays down to the error of the Signaller are OC if I remember correctly.

If there is any doubt then it is likely that Control will dig deeper until they find out. Delays involve compensation between companies and are therefore taken a lot more seriously today than they would have needed to be thirty years ago.

All modern computer-based interlockings, such as SSI and Westlock, have logging built in so the S&T Technicians can quickly identify what happened, including exactly what the signaller has done, so it cannot be "covered up" without a wider conspiracy.

Delay attribution guide link, but not sure if it is the most up to date version. http://www.networkrail.co.uk/browse%20documents/network%20code/network%20code%20and%20incorporated%20documents/delay%20attribution%20guide/delay%20attribution%20guide%20archive/delay%20attribution%20guide%20-%20may%202010.pdf

Don't know quite what you have against unions Mike. My experience is that union reps, like the people they represent - the railwaymen and women doing the job - are (almost always) people of integrity. Union reps, too, have a job to do. In my experience of them they were generally very good at it. But they wouldn't condone dangerous practice. That's not the same as refusing representation - as in the legal system, anyone accused of an offence is entitled to a rep whose job it is to try and get the best deal for them, and management knows and accepts that. (Managers, too, normally used to be people of integrity committed to doing the best job they could in the best way they knew.)

I don't know how it is now, but in my day Regional Reps - although employed full-time by the union - were subject to regular re-election, with no guarantee they would keep their job. Management co-operated with that - their jobs (and seniority) remained theirs, to come back to if they left their union post. (I'm not so sure they couldn't do turns on Sundays & such as well, a way of keeping their hand in.) They were practical workface people, in touch with the people they represented. And that meant they, like their colleagues, knew whose lives could be on the line if someone did something dangerous. And if it was a mistake - even a very grave one - unions and management alike would accept that the worker must be removed from their job (as much for public confidence as anything) but would ensure they were placed in another suitable job as 'punishment', for the very best of us make mistakes (and I know for a fact I'm not the only one who reads of an incident and thinks "...there but for the grace of God..."). But if someone deliberately flouted the rules and deliberately behaved in a way that put people in danger, the rep would do his job (including representing the member on appeal) and would be only too satisfied with the inevitable outcome.

It works well. It has done for many years. No-one makes a political problem of it, no-one needs to. If anything, both sides realise it keeps things honest - there will be scrutiny and that is as it should be!

This topic has drifted somewhat, nevertheless I have a question regarding the taking-down of signals.
I respectfully ask that this picture be considered in detail.

[img size=400]http://canis.dynu.com/~lee/LJ/SimSig.png[/img]
click HERE for full size

2B80 is delayed at Burgess Hill and has had it's signal removed.
1F64 has dropped it's rear coaches and is set to depart in a minute or two, but is still stationary for the time being.
2A68 had just this minute reported it will be delayed, and it's signal has been removed, subject to a 120 second wait.

My question is this:
Wouldn't the driver of 1F64 prefer to have his signal removed, and wait two minutes to be redirected onto the empty Up line instead of becomming stuck behind 2A68 for twenty minutes while the correct food trolley is arranged?

2B80 woulld run first assuming its running to time, but yes you're quite right. 1F64 could run down the up to reduce delay. IRL this would be a contact signaller message to the driver to confirm the situation and replacement of the signal. Simsig doesnt currently have that facility.
