Using a combination of red and green LEDs in what looks like a single aspect head allows three aspects to be shown to the driver as red and green together produce yellow. NR have installed many of these around their network.

Just seen a D stock trailer heading north on the M40. Saw another one yesterday as well. Unfortunately, I wasn't able to get the numbers.

Yes, on purpose! They say that they even know one of the gang involved!!

There is a signal box at Quainton Road but it is not a Met box. This was burnt to the ground by BR just 3 days before the site was taken over by the railway society in 1969.
The box now at Quainton Road is a LMS version of a Midland Railway box (built in 1941) that was moved by the railway society from Harlington on the Midland Main Line in September 1980.

I have just noticed a new signal has appeared on platforms south of Baker Street (might be north as well but I haven't been that way to look yet). The signal comprises a silver coloured box at high level near the middle of the platform with a three way facetted face. There is a white light on each face and these seem to come on just before the doors close so I was wondering if these signals are to tell platform dispatch staff that the timetabled platform time has expired or do they have another purpose?

Not sure about the dust but you get a similar effect passing the site of the old Down Street station - eastbound in particular.

For those long-in-the-tooth like me, will remember that before the end of steam hauled trains (both on the Underground and BR) there were virtually no trees on the embankments largely to reduce fire risk and to provide hay for the shunting horses. The cost saving decision to stop keeping embankments cleared of undergrowth and trees while improving the situation for wildlife and reducing noise has created other costly problems. The dreaded 'leaf-fall' is the most obvious one but embankment stability is another. It is true that some trees may contribute to the stability of an embankment or cutting but some varieties (Silver Birch is one that comes to mind) have a flat root ball and can make things less rather than more stable.
The increase in vegetation has also allowed the embankments and cuttings to be become home to burrowing mammals (foxes, rabbits, badgers etc.) which can also have an adverse effect on their stability.

As a frequent traveller from Marylebone into central London, I have been enjoying a much nicer journey since the Bakerloo platforms at Paddington were closed. This got me thinking..... If passengers from Paddington are filling the trains now, how much worse will it get when Crossrail opens and Chiltern complete the link to Oxford station? Is the hope that some passengers who currently use the Bakerloo will use Crossrail instead; I hope so.
If the situation on the Bakerloo gets worse, I wonder about the practicalities of opening a station on the Jubilee because the tunnels already pass under Marylebone NR station.

Comparing Met 1 with a Terrier is a bit like comparing a race horse with a cart horse. Met 1 has 66" (1.524m) driving wheels while those of a Terrier are only 48" (1.219m) Also Met 1 has a tractive effort of 14515 lbs against only 7650 lbs for a Terrier.
I have driven Met 1 from Harrow-on-the-Hill to Amersham for Steam on the Met in the 90s and while I don't have a record of the top speed, I recall it being in the 50s.
The Met engines were designed for rapid acceleration in the tunnel sections the first worked in and this gave them big driving wheels. A by product of this is a good top speed; think of the Sterling Singles on the GNR and some of the GWR's early locomotives.

Not certain but I believe that one of the indicators is at Quainton Road and I think that it going to restored to working order with LEDs and not fluorescent tubes and I was told that one went to the LT Museum.

On a similar theme - last Wednesday (20th May 2015) something odd happened on an outer-rail circle line train. I boarded at Sloane Square about 15:15 to go to Paddington (final destination - Edgware Road) but when the train arrived at Bayswater there was an automated message stating that the destination of the train had been changed and it was now Aldgate - to be greeted by laughter from my fellow passengers. The driver then came on the Tanoy to confirm this.
Is this a common occurrence?
