Is there a particular policy on level boarding in the Underground? For example, is it uniform or does the level difference between the train & the platform vary from line to line and train model to train model?

differs from platform to platform, line to line and stock to stock.

Is the difference a lot though? Merseyrail trains, for example, seem to have quite a big step, meaning a member of staff is required to provide a ramp for disabled passengers.

I assume that any new lines & trains must feature level boarding?

New lines yes, new trains not really, although rolling stock design will endeavour to minimise the step / gap.

Don't forget some platforms are served by Tube and Surface stock trains (Ealing Common & Rayners Lane to Uxbridge) so a compromise height between the two is required... Same applies to the Bakerloo Line north of Queen's Park.

On some Victoria Line platforms small ramps have now been built to give a portion of the platform step-free access, a bit messy but cheaper than raising every platform.

Some are huge... Ealing Common to step up / down to a District Line D Stock was massive, some elderly people would literally just stand there staring at the height difference and refuse to get on / off... I think the station refurb a few years ago evened out the step a bit though...

plus you have the problem where the platform curves, so in places the train hangs over the platform and in others there's a huge gap.

On the central line, some parts around Leyton and Stratford are very rough and use the old wooden sleeper tracks. Are these likely to be replaced anytime soon?

Also the other morning (I get the 5:40) I noticed on my phone that the train which passed through Buckhurst hill station before me was listed as 'Special'. Does this mean it was some form of engineering train or would it simple be a standard train which needs to get to a certain siding?

Also why I am on the subject of Buckhurst Hill station, have you ever walked around this station? Its such a shame, for it is a great example of a late victorian station, yet due to the collapse of Metronet the planned refurbishment that was suppose to take place about 2 years ago never came to fruition. The station is really starting to fall apart, plaster falling off walls, damp bricks falling apart, paint flaking off.... For what I presume is a listed building, they really have got away with murder.

I think you've answered your first question yourself with your observation of Buckhurst Hill station becoming tatty due to lack of investment post-Metronet collapse. There is a rolling programme of track replacement resulting in concrete sleepers and continuously welded flat-bottomed rail, but the foot has come off the pedal due to financial constraints and we appear to be returning to the 'mend and make do' culture of replacing sections of worn bullhead rail on the worst sections which is just a temporary fix.

Regarding the 'special' train, does your app work off the timetable or off actual train positions do you know?

If it's a timetabled 'special' at the same time daily it's most likely just a timetabled empty stock move at that time of day, maybe ex-Loughton sidings. If it was from live information, it could have been an engineers train returning towards West Ruislip after an overnight engineering job, or simply a train running empty due to a defect, graffiti, etc.

If i saw one of the engineering trains going through a station in central the urge to jump on one of the flatbeds would be very strong!!!

If it was a late train on a friday or saturday - i could well be in trouble!!!

Happens all the time... That's why there's a battery loco at both ends with a driver in each... the rear driver is watching out for just that sort of high jinks.

Try it and you'll get a loud blast of the horn followed by some very colourful language

On page 55 of my Brown (2nd edition), you can see the layout of the old sidings, but without any geographic references - maybe the author can help?

As far as I can tell, the two running lines are positioned as they have always been, with the line toward Farringdon on the left entering double track portal 1, the line toward Barbican in the middle coming out of single track portal 2, and the empty double track portal 3 only ever having accommodated a single siding (recorded on P55 of my atlas). Smithfield sidings diverged off the left-hand track and in the map below you can just see the points positioned just outside of this portal.

The map's from 1877 and is useful because it predates this section being covered over, I've rotated it 90 degrees so it aligns with the picture view, as you note in the modern photograph the Circle / Met / H&C Lines remain covered and are not visible.

No worries... It is / was a bit of an odd set-up

The Smithfield Central market buildings which the 'Widened Lines' (now abandoned ex-Thameslink route) skirts underneath are the same vintage (widened lines were completed 1866, market buildings built 1866-1868), maybe there was just a bit of futureproofing with room for an additional 2 roads provided for under the market? I'd be interested to see if all 3 tunnels emerge at the Farringdon end, or if the one I designated 'portal 3' is a dead end.

Interested enough to go and take a look?

It's only about 10 minutes walk away, but I think it would be hard to get a clear view with the hoardings at the moment.

This would be a good view but for the bloody crane in the way



Anyway looks like the ramp down to the worksite obliterates the old tunnel portals so it might be hard to ascertain. I'll thumb through a few books I own to see if I can get any old views of the portals...

The tunnel portal for the route southwards (Snow Hill Tunnel?) looks to be quite a bit wider than two tracks there.

It is, there are or were sidings there, used for peak stock when Blackfriars terminators continue to City Thameslink. All in the past now I think.

The sidings always were accessed from the south (City Thameslink) end, known as Smithfield Sidings there were once 4, now 2. What you can is the raft which covers them; until recent demolition there was a building with foundations at track level which effectively limited the northern portal of Snow Hill Tunnel to 2 roads, and I don't think it was ever any different to this.

Here's a mid-20th century view looking north towards Farringdon out of the northern portal of the Snow Hill tunnel, the little siding was where a banking engine resided to help push goods trains up the steep incline to Ludgate Hill Station. The banking engine is here in the photo, about to couple onto the rear of the train from which the photo is taken to push it up the gradient.
