Triple Tunnel Troubles (Tunnel 1)

Tesco Tunnel : Truth Told - Part One

Gerrards Cross station is at the foot of a cutting with a sloping access called, imaginatively, Station Approach.
Frankly, the station hasn't changed much since the picture below was taken in 1906.
It is much the same back in the days of sombre and boring all-over blue diesel unts
There is quite a bit more building scattered around! And there are now only two tracks not four!

But hold on, observant reader; where did that tunnel come from?
And there it is again, this time at an angle viewed from above Station Approach.
If we go to the top of the tunnel where once we would have been standing on an arched road bridge ...
... we can gaze down upon trains, platforms and footbridge. But if we turn through 180 degrees we find a Tesco store ...
... where once was a cutting. And here it is from the air.
And a similar elevated vista showing the tunnel mouth (bottom) at the end of the station platforms and the exit from said tunnel (top)..
Now, it is not unknown for a tunnel to be opened up and replaced with a cutting. fbb remembers Broomhouse Tunnel just north of Chesterfield on the line to Sheffield.
It was quite short (92 yards) and in need of repair.  See its smallness on an old map; it lies just beneath the "B" of "The Brushes".
Rather than repair, it was removed completely!

The modern map shows the cutting after opening up.
On electrified lies it is easy to build property over the tracks, even over station sites and in short-of-land urban areas this is often economically viable. And there are no nasty diesel fumes to contend with. 

For example, the process at Wembley Central began in the 1930s with a much wider over bridge to carry shops ...
... but now much of the station is covered with development.
The station is almost completely "underground" ...
... with platforms on the West Coast main line tracks (numbered 3 and 4) hardly ever used.
But Gerrards Cross?

It was Tesco what done it!

In the late 1990s, Tesco was in a burst of expansion and desperate for a good site in Gerrards Cross. There wasn't one.

So Tesco (with the help of a few lads) created their own site ...
But what happened next caused a few red races.

TO BE CONTINUED TOMORROW

The Puzzle Picture
fbb should, perhaps, have revealed that it had no direct connection with any pubic transport topic!
It does have a very tenuous link to railway modelling!

But here is a clue.
The flush was operated by a simple siphon whereby a plug of water was lifted through a "U" shaped pipe to set the siphon going; the water then flowed until the tank was empty. The refill was controlled by a floating ball valve which sank to the bottom of the tank and then opened the inwards flow of filling water.

Seemples.

Modern "faculties" are much more complex but still operate on the same principle. The puzzle picture is the thingey you press in the top of the cistern.
This bit of plastic had broken. Upon investigation, your wise and wonderful author thought the plastic was polystyrene and thus stickable with modeller's polystyrene cement.
The cement is more of a weld so should be strong enough to make a viable repair.

So the shiny bit screws into a white plastic bit that looks like an upside down uncovered lampshade, then clips into a white box out of which passes a yellow tube.
Apologies for the technical vocabulary!

It was mended on Monday afternoon and was still working yesterday evening at bed time.

Thus fbb saved the price of ...

A new push thingey OR

A new under the lid unit OR

A complete new flush and valve system OR

A brand new ceramic cistern & works.

... for about 3p worth of model railway cement!

Roger French Riding Forth At Firth Of Forth
For fbb, there were ny real surprises in Roger's blog of yesterday. He was riding the Stagecoach autonomous bus from nowhere much (Ferrytoll Park and Ride) to nowhere very useful (Edinburgh Park) via the bus only original Forth bridge.

The leaflet was enthusiastic (it could be nothing else) but somewhat misleading!
That's £6.1 million of my money and yours being wasted - yet have they seen the price of lamb chops?

Ruger was uneasy about the technology ...
... explaining why seatbelts are compulsory!

On his ride, Roger noted numerous occasions where autonomous mode had to be switched off because, apparently, the technology could not cope! These places were at all the tricky bits, i.e. the two termini.
Roger's conclusion was politely inconclusive,
"Then what" indeed.

Lets hope Stagecoach are getting well paid for this very expensive experiment!
You will find the whole blog by searching for "Bus and Train User". Enjoy!

Autono muss Omni buss : What a Fuss (3)

Remember Children's Favourites?

Ah, the contented days of listening to the Light Programme on Saturday mornings on the wireless, enjoying Children's Favourites with "Uncle Mac". It morphed into Junior Choice with Ed "Stewpot" Stewart and became more pop-music orientated. But occasionally the good old songs re-appeared. 

As a little urchin, fbb was captivated by Danny Kaye and the naivety of the king and the ludicrous response of the crowds to the self sustaining stupidity of his regal majesty! (Although your author didn't know these long words then!).

The start of the UK's first passenger just carrying driverless bus service with driver in Milton Park, Didcot, has been greeted with great enthusiasm, notably from the various organisation which have got it going.
Needless to say, Roger French has been and gone and done it. fbb has based some of his thoughts on Roger's experience (with many thanks).

But first we need to know where this driverless bus with driver actually runs.

It starts from Bee House, sadly lacking any bees ...
... which is actually an office block bringing together numerous small businesses.
There isn't much flying either!
Here the posh minibus festooned with huge amounts of expensive technology, battery powered and with so-called zero emissions, awaits its customers on the Bee House private car park, well off the public highway.

Terminus Technology Trouble
Which means that the driver of the driverless bus has to use steering wheel and pedals etc to drive it from the road to its terminus. 

Here there is a trendy bus stop sign.

The Driverless (not quite) Drive Begins
The leaflet has a map ...
... which shows three "key locations" with trendy computer style thingies (are they called "pins"?) in green. One is the Bee House itself, then further along the main road is the "Innovation Centre" ...
... which is another office block with a trendy name accommodating multiple small businesses,

After turning right into Western Avenue ...
... you come to "Milton Feast".

Yes ?

It's "street food", innit? 

On Tuesdays and Thursdays you can enjoy such things as ...,
... or, nowadays absolutely essential.
For the gastronomically less discerning, there are burgers, fish'n'chipd and lots of yummy fattening cakes!

Presumably on Mondays, Wednesdays and Fridays you starve; or grab a bite in one of the pop-down facilities dotted around - or at the supermarket down the road. The post office has migrated here from Milton Village.
fbb reckons it doesn't quite do the same job as it did in "the good old days".
But back to our driverless bus.

It continues along Innovation Drive where the passengers can watch all the innovation taking place to the left and to the right ...
... and, whilst marvelling at the innovation, they can also espy the acres of car parking space under the shade of the tree-lined avenue.

The green trees wave cheerfully at the green minibus painted blue as it trundles sedately back to Bee House for its next load of eager passengers off to buy their street food!

So the 001 route is, currently, almost useless!

Of course its use is as a test bed for the technology and the resilience of the whole caboodle. For this, Roger's experience was telling.

First, The Fuse!
Michael was he driver - very necessary it appeared.
Tim was the "second man", minder of the technology. Thank goodness for Halfords!

Bother At Bus Stops
The trouble with technology is that it is intrinsically intellectually inadequate. It has to be programed, i.e. told what to do. As any driver will know, roads in the UK are alway throwing unknowns at the man/woman behind the wheel. One problems then, is bus stops.
Roger suggested that a request push button on each stop might be an answer - that would be fun for the youff on the estates of Wigan would it not?

Temporary Traffic Light Trouble
Also, inadequate pre-programming means that sudden road works will simply cause the bus to stop - full stop,
Might make for a slow journey!

But let's be fair (if we must!) this is a trial run and the results will lead to improvements - possibly!

Peak Hour Progress Halted
Once this non-route has done its stuff as an evaluation exercise, the service will be extended to Didcot Parkway station.

Yikes! 

Milton Park is quite quiet once the innovators are in their bunkers busily innovating; but getting out of the bus stands at Didcot Parkway will be fun fun fun.
It looks innocuous in the above Streetview snap, but, be assured, autonomous enthusiasts, Station Road gets well clogged at commuter time.

How long will the technology have to wait to escape the clutches of the station stops?

Another job for the driver of the driverless bus!

The current service runs every 15 minutes with a two hour gap in the afternoon (for an interim recharge?) It is free to all and does run to a "proper" timetable.
In theory.

In his blog, Roger expresses the considered view that autonomous buses will never run on Britain's roads without a driver, which, if his thinking is right, would seem to make the whole thing utterly pointless and hugely expensive.

So ...

A view of the future or the king's new clothes?

(No reference is intended to any real king and his particular attire to be worn in a  just under two month's time.)

Look! They've got a bigger bus as well!
And a little video ...
And you all really believe that?

A view of the future or the king's new clothes?

As Danny Kaye did not quite sing:-

Th'electric bus is all together
But all together it's altogether the most ridiculous bus that I have ever seen.
These eyes of mine have once determined the speed is slower
It's not a goer; the paintwork's blue but the publicity claims it is "green".
(Lovely shade of green)
Whatever does it all mean?

Th'electric bus is all together
But all together it's altogether the most ridiculous bus that I have ever seen.
These eyes of mine have once determined it stops when no one's waiting;
It simply ain't relating when lights are red for roadworks where it's once been.
(Does it really amuse?)
Have you got a spare fuse?

Tomorrow we pay a visit to Norwich.
