GWR 'Small Prairie' no 5521, masquerading as London Transport's L150, leaves Horsted Keynes for Sheffield Park. I don't much like this but thought I'd post 'for the record'.

The Royal Norfolk Show and it's day one and the sun is out. The barometer is set fair and temperatures are soon in the 20's as thousands pour through the gates for Britain's largest two day farming event.

The day before the showground has had a thorough soaking as the heavens opened. But it was sunshine all the way as town and country mingled, if never quite meeting, as is often the way, at the Royal Norfolk Agricultural Society's annual event. Ladies wore bold hats. And why not. There were prizes for them too as well as for the best turned out bull, sheep or sow.

The Royal Norfolk Show is the largest two-day agricultural show in the country. There’s more than enough to interest everyone; from the latest farm machinery, and livestock to sampling some of Norfolk’s finest produce. So whether you are visiting for business, education or just pure pleasure you can be sure of a great day out.

The concept of the train was introduced to the Indian media at a press conference in central Delhi. Part of the conference involved a preview of the train - made from cardboard.

Signal is a collision of stasis and movement.

Signal is distinctively non-kinetic.

Signal relies on perspective and expectation.

Signal is mostly air.

Signal’s non-air parts aggressively catch light and harvest shadow.

The work’s title derives from the engineering term “signal-to-noise ratio”.

This is the cabinet with the Phoenix Diamond traffic counter. The detection bay looks odd, with missing detectors and detectors partially pulled out. The reason is that when we worked with Diamond, they told us they could take a contact closure output from a traffic signal detector to place a contact closure into the count station. The cabinet was wired to accommodate this.

When we actually set it up in the field, we found that there was a difference between what Phoenix thought how detectors worked, and how they actually did. They wanted the voltage on the input to drop from 24 volts DC to around 0 volts DC to place the contact closure onto the count station. In reality, the traffic signal detector output drops to about 6 or 7 volts which is enough to trigger the traffic signal controller detection inputs, but not the count station detection inputs.

We worked on several fixes, but ended up getting the module for the count station that allowed it to be wired directly to the traffic signal loops, bypassing the vehicle detectors.

I was not particularly happy, as we bring back our loop wires in 4cc/s wire, with a pair of loops on each wire. We run these through a scanning loop amplifier, so we don't get cross talk. This has worked OK, but we are looking to modify it this year to provide better data.

The Invensys Rail Signal is one of the most popular new signaling systems for the nation. This system is slowly replacing the older crossings throughout the nation. This signal is installed at the East "D" Street crossing of Sonoma-Marin Area Rail Transit's tracks and the Lakeville Highway at East "D Street.

Years later extra platforms add, the signals needed numbering, so spare numbers don't match the rest of the platforms signal numbering.
