your right EC100 does not work due to the power pack operating the inductor rail does not work
WM400 i took out of commision as a train and hit a section of the inductor rail damaging it but i believe this had the same problem as EC100
EJ100 does work now the orignal fault was just a faulty link between the inductor rail sections

One point is though WD400 and EC100 and EJ100 have all got a delta track to activate the following signals even coming from hanger Lane to Ealing common the outer home ( 100 ) signal has got a delta track but FF60 hasn't? Why is this? FF60 has a position detector - the more modern (and more accurate) equivalent of a Delta Circuit. I would be very surprised if the FF60 timer didn't work as the circuit has only been commissioned for two years. |

i never seen a axle counter but they are called sieman's wheel detectors they are very good but if a can was near the rail its connected to it shows the track as beening down they are alot more accurate then the older delta style track circuit which detects a train either side of the point it connects to the rail (known as the injection point) to about 30ft the wheel dectector off the top of my head is just a few feet either side

the DLR uses the sieman's wheel detector it stands about 15" high beside the track and has a yellow painted box on top

Something has been puzzling me about FF60's If that signal is at danger RFF60 will obviously be yellow. Now any driver seeing a yellow is going to apply the anchors and therefore slow down. Having done so he will approach 60's at much reduced speed and so within the limit.
So if there is a timing section for 60's why does it not work and clear said signal and let the train up to 59's? I strongly suspect that my first theory is right and it is a signalman who is playing trains or does not know his job.

Here is a photo of a DLR axle counter www.xs4all.nl/~dodger/axlcount.jpgThey are used for train detection around switches, and also as a back up fixed block system. Seltrac's normal train position detection and communication is done using inductive loops laid between the tracks. |

a siemans wheel detector looks very simular to the DLR version and does the same job

Well how strange - ever since I had a moan about FF60 when I started this thread on the 8th of Dec how now I find that FF60 seems to be behaving itself  I haven't been held at it once since then and when I approach it when it is at danger it clears  Thank you everybody for your input about this problem and Thank You to whoever you are that has cured this problem, it just goes to show that a site like this can work wonders if the right buttons are pressed ( excuse the pun ) Thanks. |

Yes, I've gone past it twice today and it worked fine for me too.
