    Buddleia roots and the damage they cause.

    The problem is the off-track department are snowed under this time of year with reports of obscured signals, spraying giant hogweed, treating Japanese knotweed, and all their usual fencing and access point tasks. There’s lots of stuff I’m sure they’d like to do as much as we’d like them to do...

    Low-speed, empty stock derailment at Bletchley (26/06)

    It left Bletchley wrong direction on the Up Slow.

    Identifying these signals

    That’s a Dorman iLS signal.

    Sign language on departure boards

    I haven’t met anyone, but have come across people in other online spaces who are Deaf, and often the syntax of their written English ends up being quite similar to BSL. It really wouldn’t surprise me if they struggled to parse complex written English as well as the languages are so different. A...

    WCML Signal 113 (near Primrose Hill tunnel) fault

    I don’t know in this specific case, but components can degrade overtime and become less effective at filtering out interference or cables can be damaged. The level of interference can also increase beyond what can be filtered out, this has happened in a few different places where there has been...

    How hard is it to get in to a Level 3 Rail Engineering Technician Apprenticeship with Network Rail?

    When I applied eleven years ago there were 2000 applicants for an intake of 200. I have no idea what the numbers are like these days, but I doubt it’s easy. For the presentation make sure you actually prepare something, choose something you’re interested in, but also think about the type of...

    Can 3 lens signals display preliminary caution?

    You can have signals where the filament lamps have been replaced by LED light engines. It’s just a direct swap from filament lamp to light engines, so they work in exactly the same way as the filament lamps did, but lit by LEDs.

    Concrete v wooden v composite v metal sleepers - How are they selected?

    Saltcoats was replaced with axle counters in the late 90s

    Concrete v wooden v composite v metal sleepers - How are they selected?

    The guidance I’ve read from 2024 states: “Cat 3 to 6, not in platforms, 3rd rail areas, jointed track, or locations where salt corrosion is likely, not on curves less than 500m. Strengthening/guard rail designs also available. Refer to TRK2102 for all restrictions of use” Not my area of...

    Concrete v wooden v composite v metal sleepers - How are they selected?

    Although some polymer versions have been found to be rather less fire retardant than they claimed to be.

    Concrete v wooden v composite v metal sleepers - How are they selected?

    Looking into it a bit more it's guidance rather than forbidden, but would make sense to give other options preference in salty environments.

    Concrete v wooden v composite v metal sleepers - How are they selected?

    As far as I know new timber sleepers aren't available any more, with composite being the replacement. I've certainly seen composite around a few more places recently, although it is quite hard to tell as they do look very much like brand new timber sleepers. The first time I saw them no one...

    Survival Tips for Hotel Living

    Take an extension lead, hotels rarely have enough sockets where you need them. Your own coffee too, as it's generally naff and if you're not getting the room cleaned everyday you'll run out anyway.

    East Kilbride/Barrhead electrification updates

    I think RTT has got slightly confused unless they were testing time travel abilities. Looks like RTT is displaying the time for some of the return journeys rather than the outward journeys as the times jump back and forth, e.g. passing Clarkston at 1611 (+25), Busby at 1651 (+64) and then...

    Does going down the ramp constitute trespass ?

    On the east-bound platform the path is perpendicular to the track, so the barrier is there to ensure people turn and don’t carry on directly onto the track. On the west-bound platform the path runs parallel to the track so you’re heading the right direction already.

    GWML ATP

    We had the second and third varieties then, I’m too young to have experienced the first. The third variety was definitely worse to carry as it fascinated us that they’d managed it! At a guess it was an extra 6 inches wider and slightly deeper too.

    What triggers the signals to change to danger (red)

    No, the track circuit is the “sensor”. In its simplest form* a track circuit is an electrical circuit which uses the rails like wires. The track is divided into sections with Insulated Block Joints, and a power supply is connected to one end of this. The other end is connected to a relay. When...

    GWML ATP

    Plus ATPLIT is almost exclusively pronounced as a word in my experience, and a word that’s morphed into something closer to “Atlip” to my ears. If you spelled it out most people would give you a strange look and have to have a think about what you were referring to. At add, the TSR and No SR...

    GWML ATP

    Possibly a slightly different design then, our PSU/charger had always been separate and remained the same. The first ones we had were as pictured in the “Living with ATP” video (screencap below), although significantly less square and held together with someone’s old belt by that point. The...

    GWML ATP

    I left the Western three years ago so my information is a little out of date, but certainly then it was fully operational, and there were spares on the shelf. We had recently got a new ground tester just before I left (somehow managing to make it even bigger and awkward than the old one!) and...
