Not what I am thinking of anyway. It was a wider political crisis.

 

[theageofthetra]

The Suez crisis meant there was no fuel to run the bus services that had replaced the train?

 

[Marton]

Correct. Suez. I understood more about petrol rationing than buses, but the right concept.

Over to you.

 

[theageofthetra]

Name some occasions when a train will intentionally not show a red light to the rear.

 

[Welshman]

When it is waiting for another unit to be coupled-up to it at the rear, and the unit to be added is near?

 

[t_star2001uk]

When making a wrong direction move more than 400 meters.
Intermediate cab of coupled multiple units.

 

[theageofthetra]

First one of T Star's is correct, there are others.

 

[t_star2001uk]

Not on TCB with a divided train. Only attach a tail light when the front portion reaches a signal box or goes into a TCB area.

When leaving a traction unit on a dead end line with a white light on the stops, a white light must be shown on the end of the traction unit.

 

[theageofthetra]

Thats the ones I had, your floor

 

[t_star2001uk]

Bit of a historic one this. There are 15 exceptions for passing a signal at danger. What was number 16???

 

[cjp]

No idea but I would be interested to know the other 15

 

[Tomnick]

In the absence of any other guesses then, I'll have a go. In years gone by, the clearance of a subsidiary signal was considered authority to pass the main signal at danger, and was shown as such in the Rule Book. Is that what you're looking for?

 

[t_star2001uk]

Sorry. No thats not the one. The one im thinking of hasnt been in the rule book for quite a few years now.

 

[theageofthetra]

Its not some wartime oddity is it? Whereby if an air raid was taking place you could try and get your train to a place of safety e.g a tunnel?

That would be passing a signal for shunting purposes.

No. Not some wartime oddity. It was only removed from the rule book in recent history.

 

[Llama]

Passing the section signal of box A to proceed through the section and check why box B has not opened / switched in?

 

[t_star2001uk]

Ok here is a clue.


It was a method of working that allowed a train to be authorised past a signal at danger.

 

[Whistler40145]

Guard on a multiple unit giving Driver the right away buzzer code even if signal is set to danger?

 

[t_star2001uk]

That will not be authority to pass a signal at danger.

 

[theageofthetra]

Just to clarify is it a former rule that allowed a driver to authorise themselves to pass a signal at danger i.e without authorisation from a signaller/pilotman?

 

[t_star2001uk]

No it was with authority of the signaller. And yes it is not in the rule book now, it was in the older black rule book.

See post 2627...

 

[Xenophon PCDGS]

No less than 10 days have elapsed since the last posting.

 

[t_star2001uk]

Ok

The answer i was looking for was Time Interval Working...

A train is authorised past a signal at danger and then after an elapsed time the next train was allowed into section.

Not in the rule book anymore IIRC it was deemed as not suitable for the modern railway.

OPEN FLOOR

 

[Tomnick]

Being pedantic, maybe, but the 1972 Rule Book shows 15 reasons for passing a signal at danger with authority, and time interval working was alive and well then - it's covered under the general "passing the section signal at danger because of a block failure" (now incorporated, as far as I can tell, into "defective signalling equipment"), the details of the time interval working being covered in the signalling regs.

 

[cjp]

Name the rather large station served by trains from both Victoria and Waterloo

 

[steamybrian]

Clapham Junction

 

[cjp]

Clapham Junction

Quite right

 

[steamybrian]

What is unusual about signal SVR901 on the Spa Valley Railway...?

 

[Marton]

Jointly controlled by NR and SVR?

It is true it is operated by SVR staff with permission of NR.

Can you be more specific and say what else is unusual with the actual signal...
