Heading towards the Aldwych is RM1776 showing off it's adverts for the British Museum.

RM1941 looks resplendent in the afternoon sun outside Charing Cross station.

From 2006, starting off with the 9, in the Strand in the bright April sunlight is RM1640.
The difference between the First & Stagecoach examples apart from the gold company names is the front number plate. First use silver on black.

Some Marshall Refurbished Routemasters started in November 2005 on the 9 & 15 for tourists, covering parts of each route. Each route shows just plain 9 or 15, but they are known as 9H and 15H.
Each route requires only 5 buses plus 3 spares and they run from 09:30 to 18:30 daily on a 15 minute frequency.

It is sensible that the 9 finishes at the Aldwych in line with the main service, but the Royal Albert Hall is not really a traffic objective. Kensington High Street would be a better place to finish. Having to throw passengers off to catch the bus behind is not good customer service.
For Route 15, starting at the Tower is again a sensible move, but I question finishing at Trafalgar Square. With the main 15 being truncated at regent Street during 2010, perhaps the Routemasters should also finish there.
TfL do not like or encourage buses turning short, yet these routes have been deliberately designed not to cover the full route which I have seen causes confusion.

RM1933 looks very smart on layover just round the corner from Trafalgar Square - note the white on black registration plate.

At the Royal Albert Hall is RM1627, with passengers having to disembark and wait for another bus to continue their journey.

I just about caught RM871 at the top of Whitehall as it pulled away to take up its line of route. I had forgotten how quickly the Marshall refurb buses can pull away!

From the running day on 17th September 2006, I was lucky enough to get a ride on RM1.

Also making an appearance was RML2760 so we have the first and last RM's on the same day!

Unusually showing Aldgate as a destination, RM2089 was on the 15 at the Strand on 21st November 2009.

Also on the same day was RM1218 on the 9, with a via blind comemmorating 50 years of Routemasters on route 9.
