- Pendre is a small station and control point on the Talyllyn railway in mid wales, this busy little Blockpost controls both the section towards Tywyn wharf station and the section north towards BRYNGLAS (covered in another video) , as well as controlling the locomotive sheds and carriage sidings here.
We see a busy mornings operation getting the empty coaching stock out to go towards Wharf station as well as some engineering and locomotive movements under the watchful eye of signalling Inspector Dave, who is our guide upon how all things work at Pendre Blockpost.
Our thanks to Dave and the staff and volunteers of the Talyllyn railway for letting us behind the scenes for a day.
Телефоны и сигнальные устройства моё увлечение, я их реставрирую и коллекционирую. Получил огромное удовольствие. Спасибо!
Thumbs up.The little dial indicators are interesting,they must date back untill before light bulbs were invented.ha ha.
Cheers.
Yes,internally the two position ones are basically electric motors and the pulse throws the coil and needle across momentarily. The three position ones also have stop pins inside that need to be pulled out the way of the needle indicator
If you want a good tale I know one indicator that used a small servo from a WW2 v2 rocket that still works to this day.
@@irseminorrailwayssection9491 Thanks mate.I used to work for br& saw some very old stuff from time to time.
Another fantastic video. It's a shame there isn't much shedding light on the quirky arrangements on the TR, but this does it justice.
A couple of questions. Is there a reason why that instrument is painted yellow? Is it mostly to distinguish it or is it something else?
Second, on narrow gauge, what is the overlap from a signal on the TR? I've always struggled to get an answer for narrow gauge overlaps and siting distances, so this seems as good opportunity as any to ask! And lastly, are there any bell codes specific to the TR's rulebook or are they all straight out of the RSSB/BR handbook?
Aha wait till the next one and that’s actually covered 😃. Itl be. Couple of weeks till release
The four machine colours are red,blue,yellow and green it helps with getting the right key issued and put back in the right machines
Traditionally the overlap goes as far as the exit boards at the other end of the loop of old board. It gives a large overlap but ensures safety better
@@irseminorrailwayssection9491 A correction to what you say about overlaps on the TR. Bearing in mind the statutory speed limit on the TR is 15mph, the overlap for the home signal or stop board is as far as the limit of shunt at the loop in the opposite direction - at Brynglas for down trains this appears to be around 20m to the up direction limit of shunt, although I haven't measured it. For movements into the loops, the fouling board at the far end of the loop acts as the limit of the movement authority, the overlap for which is to the Limit of Shunt in the same direction. If I could work out how to attach a diagram to the comment I would do so to explain more clearly.
On bell codes, the majority would be familiar to anyone knowing the BR codes, but there are specials to deal with specific movements in the rule book - for example a special train entering section code of 1-2-3 used most often between Wharf and Pendre when the train is propelled (engine at rear with driver, responsible person in front vehicle).
@@stevehailes684 so is 20m more or less used universally as overlap distances then by narrow gauge lines, or is there some other mechanism used to determine this? I ask because there's next to no information on this sort of thing.
Beautiful. Who were the makers of that lever frame? Was it only used since the preservation period?
Yes the TR being early preservation pioneers did install much recovered frame equipment from elsewhere
@@irseminorrailwayssection9491Is the frame McKenzie and Holland?
@@Mason58654 I’d say more a standard or RSC company type , think spacing were 4 inch centres
