Hi all, I am working on a project to do with absolute block signalling based in the southern region, and I have come across the Sykes block indicator, which apparently was the main block indicator used in the region. What was the commutator locking slide for? Thanks  Post has attachments. Log in to view them. Log in to reply |

The slide would be used in connection with T3 working. Once the PICOP had his signal protection the instrument would be turned directly to train on line, not passing line clear and not collecting £200, although if you failed to do this you would probably meet with a nurse to collect a pot for providing a sample. On a serious note the slide would then lock the instrument at train on line to prevent you accidently placing the instrument to normal.

Is it used only with T3 working or just generally when the indicator should be at train on line?

I've only seen it used for T3 working, although I suspect that you could use it anytime that you want to ensure that you wanted to ensure that there was no means to return the indictator to line normal. Paul You have to get a red before you can get any other colour Log in to reply |

The modern rule book states that a block instrument reminder such as this is to be used when A train or vehicles are detained or left at the home signal or within the clearing point and when a train ir vehicles are left in the block section. Also when maintaining the block indicator at train on line for a possession or a line blockage. They should also be used when blocking back or when placing the block indicator to train on line due to an obstruction or other emergency.
