Clyde Tunnel Smelling of Coconut Biscuits

Would you like to smell coconut biscuits as you drive through the Clyde Tunnel in Glasgow?

Maybe you would rather see leprechauns, or favour having the inner walls lined with old CDs?

If so, you are not alone - these are just some of the suggestions received by the woman who is hoping to light up the lives of the thousands of motorists who use the tunnel every day.

Kathy Friend took matters into her own hands after becoming fed up with the "grim" look of the link.

"That run of concrete and grey buildings is a rather depressing thing to greet you," she said.

"I thought it would be improved a lot with lighting.

I hold my breath going through the Clyde tunnel.
I find the best way is to breath normal and then just stop rather than take a deep breath.
you cant smell anything when you are holding your breath.I think?

They already looked into this. As far as I recall it's gonna remain grey and boring, is it not...

There was a feature on it, and it's all dictated basically by fire regs and crap like that, obviously.

Is this woman taking the mickey or what? OLD CDs???

Hold your breath through the tunnel! Major effort! I believe at 30mph it takes 55 secondds to go from 1 end to the other never mind the stop start traffic most of the time!

I used to have to do that with my first car as there was a problem with my petrol tank and I either rolled the window down to get rid of the petrol smell in the car and stank out the car with exhaust fumes or get high on the petrol fumes.

I'd hold my breath due to the 'fumes' that you get when I go through the tunnel on an Arriva Bus, but that has less to do with the tunnel! I think 20 minutes without air might leave me dead! Mind you 20 minutes of BO, pish, diesel, Carbon Monoxide and stale Alcohol in a bus has the same effect!

and that's only from Dalmuir to Clydebank, plus of course
the token drunk, with his cheap bottle of cider before 8am

how is it you get a mobile phone signal in the tunnel but no radio?

Different frequency.

Different frequency.

Doubt it.

Mobile phones operate at much higher frequencies than radio, therefore the signal is much more directional and less able to penetrate water/ground.

I suspect there is either a repeater installed within the tunnel, or the cellular system has the area so saturated with signals, that there is sufficient signal to maintain contact with the phone and switch transmitters from one end of the tunnel to the other as you travel through it.

Wonder when that was installed?

I can't get a GPS signal in the tunnel either and it takes around 30 seconds before it reacts again which must annoy those insurance companies that track your car!

I'd heard DAB radio works in the tunnel but I don't know if that was just a rumour as I have never tried it!

Coconut yum yum I also like the smell of hot jam, like on tarts and sponges

would smell nice in a tunnel

The GPS signal strength measured at the surface of the Earth is about –160dBw (1 x 10–16 watts), which is roughly equivalent to viewing a 25-watt light bulb from a distance of 10,000 miles.

I assume you're referring to vehicle SatNav, as anyone with a handheld GPSr will know that a conventional receiver will lose signal when they go under the cover of trees.

Tunnels and intermittent signal breaks are not a problem for GPS based vehicle tracking systems as the software has track-prediction which projects the expected position when the signal is lost. If the signal is not received as expected, the system either waits to re-aqcuire, or triggers an alarm or other event, dependent on the application.

DAB uses relatively long wavelength HF as the carrier, basically a smart version of medium wave radio, so tunnels and the like don't cause the same loss of signal which VHF FM suffers.

It also uses a rather clever technology, whose name has totally escapes me, which can get signals from two different places, and improve the signal, rather than cause multipath interference.
