you prolly dont care but does anyone know a trick to get back into an Instagram account..? I somehow forgot the account password. I appreciate any assistance you can offer me
@Jasper Gunnar i really appreciate your reply. I found the site thru google and im trying it out now. Looks like it's gonna take quite some time so I will get back to you later when my account password hopefully is recovered.
I know this is quite an old video, but you are obviously keen on railway signalling. Have you tried SIM SIG .. a signal simulator. It looks pretty difficult. Regards from Whitley Bay
If a track circuit ahead of a red signal becomes occupied, an alarm goes off on the signaller's work station calling his attention to the possibility that a SPAD may have occurred.
Very interesting, if distinctly on the nostalgic side with blue/grey coaches etc! I believe signalling and train control has massively moved on now, as can be seen from the number of former 'state of the art' signal centres that are now out of use. The one thing that does strike me is that this idea of having the driver look out for signals is really getting a bit old fashioned, we should be moving to in-cab (or totally auto indeed) so we can dispense with the infrastructure required to maintain all these individual posts and signal gantries!
Indeed since the supposed privatisation of BR, the introduction of "Computer Interlocking" has revealed itself to be fatally floored on a number of ocassions. Why? Because those computer engineers designing the software, are not themselves well enough versed in the methods of railway safety. The Paddington crash being just one good example Post privatisation.
If you mean the Ladbroke Grove crash, that had nothing to do with defective interlocking. What caused that was a combination of poor signal sighting, inadequate driver training, and a layout designed assuming full ATP would be installed (which it wasn't).
I don't think you know what you're talking about at all. Interlocking requires no user interaction to work. Interlocking blocks incorrect sequences of signaler actions. It doesn't matter whether it's mechanical, relay, or computer based, it does the same thing. Indeed, there was another video which detailed a number of crashes including a fatal crash due to a lever being thrown in error exactly during a mechanical interlock window of 100 ms due to the small distance between a train detection mechanism and the switch. You clearly need to watch this video series from the beginning.
Thank you for launching this programme. I'd been really slow at grasping how signalling works, which was frustrating.

@Jasper Gunnar It did the trick and I finally got access to my account again. I'm so happy:D
Thank you so much, you saved my ass !
@Cooper Ian you are welcome :)
where I worked at Clapham Junction there was lots of equipment failures.
I had two brothers who started their signalling careers as box boys at London Victoria and a third who retired last year from Borough Market Junction.

And how would the signalman be alerted if a train SPADs?
The driver would contact the signaller and the track circuit of the section ahead would be activated.
If a track circuit ahead of a red signal becomes occupied, an alarm goes off on the signaller's work station calling his attention to the possibility that a SPAD may have occurred.
इसे देख कर तो यही लग रह है बहूत सालों से इस तनख्वाह नहीँ मिली,..थकेला खुद ही कन्फ्यूज हैं.?

Boring
Along with trains themselves no longer allowed to be trains, your expressed wishfulness is mightily buggered..just sayin .. . . .
