It was installed in 1994 after Mr. Rogers, misreading the signal by the fish tank, operated the trolley at too high of a speed around the castle, leading to a derailment that sent the trolley off the bridge. The investigation found a casual factor was the pianist was fatigued after filming three episodes in a row and had played the trolley music too slowly. Prince Tuesday was killed in the accident, but the show quietly replaced him with another actor.

@tobysummers4716 жыл бұрын
TheSaintST1 GEC signalling on behalf of Alcatel SEL and all the 165s were delivered. The chiltern system differs from the Great Western version slightly. But both work the same. ETCS or the full ERTMS is completely different. Originally the LUL section was going to get the system too but it was expensive and it eventually became impossible to engage in engineering possessions on LUL metals for this task. That’s why chiltern units have tripcocks. 1909 technology on 1990s trains at the time ! The equipment was manufactured for the LUL a section but was moved elsewhere where it was more important. Sure would have helped. Thames pinched units 001-008 and gave them back eventually to 2004 and they didn’t get tripcocks when they got back so had to run in a 4 car formation. The ATP buttons were smashed up and had to go to Ilford for replacement. There’s a pic I remember of 005 and 003 being coupled oddly because of the arrangement
@tobysummers4716 жыл бұрын
Greyclaw I believe Alcatel still supply the equipment however the supply for it is low because it is considered obsolete now. Chiltern Main line will keep it GWML will eventually rid of it and replace it with ERTMS but unlikely soon because the whole line was resignalled and taken over at TVSC at Didcot and replaced boxes such as Slough PSB or New IECC. I believe the building still exists.
@johnkeepin75273 жыл бұрын
The original plan was to use two independent manufacturers for the two systems - one for the Chilterns and the other for the Western main line and the new Heathrow Airport branch at the time. At that time, ACEC and Alcatel were separate companies, but not now. Historically, I had a fair bit to do with both signalling systems on both the Chilterns and the new Heathrow branch (along with full-on renewal and electrification between London Paddington and West Drayton). Might be worth mentioning that, at the time, not all rolling stock was fitted with it; in effect, just the new Heathrow Express ones, and the “Intercity” HSTs; not the rest of it, in particular the Network South East sets, nor any locomotives at the time. The integration of an add-on system to traditional BR signalling systems, along with conventional driving skills etc was hard work - including psychology as well; not just physical installation of extra equipment. All had much to learn along with that. As usual, money talks, and slowed down the original project, assisted by privatisation. It led to the development of the “Train Protections and Warning System (TPWS)” under Railtrack (remember them?). Later on, the concept of European Train Control System (ETCS) evolved, and in effect it has taken over the market.

Interesting video. Probably from the 80ties or earling 90ties by the look of the glasses... :) Why wasn't the system rolled out over the entire network eventually? Simply because of too high costs? The wire loop system is similar to the LZB cabsignalling system in Germany for the ICE high speed trains. It was develloped back in the 80ties. This system is still in use. It might be replace by ETCS level 2 in the near future.

ATP continually monitors your speed and can provide you with information (permitted speeds and signal aspects here for example) whereas TPWS doesn't really warn you before it intervenes and can only act on trains in fixed locations (e.g. signals). ATP will also do its best to stop you from passing a red signal (or end of movement authority) whereas TPWS overspeed sensors won't necessarily stop you before the signal, rather it aims to stop you before a point of conflict. Depending on your definition you could include (amongst others) TVM, ETCS and CBTC in "automatic train protection" as they also continually monitor your speed, I'll leave that for someone else though!

@cjmillsnun9 жыл бұрын
Sorry David, disagree. TPWS can't prevent a train above a certain speed from going over the overlap. ATP won't let the train go that fast to begin with and will stop the train. ERTMS will render it (and TPWS) obsolete though
@daveb07899 жыл бұрын
We have TPWS+ for the higher speeds. There's not been train crashes as a result of the current TPWS system failing to stop trains within the overlap. (Yes there have been trains with defective brakes such as at Crewe where speeding was involved and the driver had no proven route knowledge or low adhesion incidents which the system wouldn't stop anyway. ERTMS is the answer but in the meantime ATP is in its present form horribly inefficient. For example it can't tell the train if the aspect changes to a less restrictive one until the train gets to the balise near the signal. It is an intermittent form of train supervision. What this means is if a signal changes from red to green is that the driver can't accelerate under ATP until the signal is reached despite the fact he/she can see the signal hundreds of yards away.

+David S Extra layers of safety is NEVER "Unnecessary". What happens is one system failed and the train's computer fails to detect that failure due to some software or hardware bug? Computers and electronics can and do go wrong. The class 220/221 Voyager (plastic snot-box) is a perfect example.

+David S Relying on one system alone is never a good idea regardless of how good anyone thinks is it. For example, think of the number of safety devices something like a TV in your home has (Main 80-100 amp fuse at the meter, an RCD, a MCB, plug fuse and often and internal fuse or thermal cut-out device). A train having multiple safety systems is never a bad idea. ERTMS however isn't fully rolled out yet is still under testing and development and it will be under testing a few years after it is fully rolled out to ensure the system works as designed in real world conditions. Even after real world testing, ERTMS won't be the ONLY safety device fitted to trains. If there is a human controlling the train, there will be other safety systems in place like the dead mans pedal. Technically drivers of modern stock don't "Drive" the train. They simply make requests to the on board computer which then decides based on different sensor information weather that request can be acted upon or not, just like a modern fighter jet like the Eurofighter. Modern trains like the Voyagers have no physical connection (push/pull rods, moving steel cable ect) between the power lever and the engine/traction motors. Only electrical cable which goes via a computer, that's what drive-my-wire is. Hence why on a 100mph line, a train can't go 125mph, The computer will say no (excuse the pun). The Eurofighter for example, is designed to be aerodynamically unstable and requires thousands of tiny adjustment every second to keep it in level flight, something that's impossible for a human to do since humans can only make low tens of adjustments per second. If one took the flight computers out and replace them with cable and pulleys. It would be very hard to fly and would be far too demanding on the pilot.
