There lurks on the London Underground network a tube station that wont appear on any tube map, past, present or indeed future. In use on most days, yet no trains ever call there and no passengers ever use it. Fully fitted out with Oyster card readers, signalling and display boards, it isn’t an old abandoned station.
This is in fact a fully fitted out fake tube station built by London Underground on the 3rd floor of an office block in West Kensington and is used to teach new employees what goes where and when.
It is slightly surreal to go into a fairly generic office building, then on the third floor, find the entrance to a tube station – complete with fake newspaper stall and wire mesh grills.
The whole floor is used for training staff.
Despite the presence of the mocked up tube station, the rest of the floor is made up of conventional office rooms, although in a nice touch, each room is also named after a former tube train stock number.

The tube station is probably the highlight for any visitor and in addition to looking like a tube station, it also behaves a bit like one. When a train is due to arrive, although no physical train appears, the platform rumbles, speakers drown out conversations and there is even a fan in the corner blowing to simulate the wind blast that heralds the arrival of the train.
How the tube network deals with faults – and what causes them. For example, there is a small break in the running rails which acts as a signal isolator, but over time that gap gets filled in with metal filing from trains, and the signal breaks. Sometimes, simply scuffing the surface with your shoe is what it takes to fix a signal.
Which is why sometimes signal failures last just a few minutes before magically vanishing.

Sometimes a signal failure in the wrong place can be a nightmare and totally screw up the network for several hours.
Incidentally, West Ashfield station is indeed in the western wing of the office block. Maybe there’ll be an East Ashfield station sometime in the future?
One floor down is the BIG BOYS TOY writ large, as there is a fully functioning training simulator for the forthcoming S-Stock trains that will be appearing on the Metropolitan Line next year (and Circle/District later on)

Quite interestingly, although a SPAD is not a good thing, in of itself it isn’t mission critical. Due to the nature of the tube network signalling systems, SPADS are almost guaranteed, and the tube network only takes action if someone is rather incompetent and keeps passing red signals. As a SPAD could be a signalling failure and not the drivers fault, the driver seeks permission to drive carefully after each incident and after 3 minutes, returns to driving at normal speed. The new S Stock automatically limits the speed for three minutes, then releases the driver to go at full speed again.
The new trains also have some interesting improvements, such as if someone has got a bag jammed in a door because they jumped on when the doors are closing, then the train will only open that one door rather than all the doors on the train – which usually results in more people leaping on (and getting stuck between closing doors).
Incidentally, standing outside the simulator as the train starts moving forward is a very unsettling experience as you see the scenery moving, but don’t feel the usual sensation of a train accelerating. Takes a bit of getting used to as your brain gets confused by the illusion of moving without moving.
A brief talk about how they use a static model railway to set up possible scenarios and teach tube staff how to handle situations.

Then on to the ultimate model railway.
This is a fully functioning model railway that was only recently built to replace an older model based in White City many years ago. That older model used signalling systems that were so close to the live kit, that sometimes an engineer would run in and nick a component to fix a broken signal at White City!
That’s not going to happen with the new model train set.
In addition to being configured with a selection of more modern signalling systems as used on the London Underground, they also have a lovingly recreated old lever based signal network which is used to show staff how things worked in the past.

The true purpose of the model train set though is to train staff on dealing with problems, and a simple flick of a switch can simulate any sort of network failure you care to imagine.
Why it can sometimes take ages to get trains out of tunnels when things go wrong.
For example, a train is stuck at a platform – maybe someone decided that 5pm was the best time to kill themselves – and there is a train behind it in the tunnel. Not only does that train now have to reverse back down the tunnel – but do so safely.
In ye olde days (aka, 2008) the station staff at the previous station would have to manually check any points junctions were safe, but then walk down to the stranded train and hand over a paper form granting authority for the driver to drive backwards down a tunnel.
Today they can grant authority over a secure radio link, but that only became possible 18 months ago. Indeed it does seem that the Evening Standard headlines of people being stuck in tunnels for an hour or more have dried up since this was introduced.
So, a change that many people wont have even known has happened has already had a positive impact on reducing delays on the network.
One of the stations is called Hobbs End. Sci-Fi film geeks may get the reference
