Another screenshot from some recent work, plus an updated savegame:

I've "refurbished" all of the First Great Western main line stock, making it "length=10" in line with my new standard. The HST is the first longer train to which I've given this treatment, and I'm pleased with how it looks. (To appreciate the difference, take a look at the
last screenshot I posted). I've also re-aligned these trains and added extra detail.
I've also added the Class 180 'Adelante' (seen heading eastbound on the fast lines, above). Previously all of my Cotswold Line services were operated by HSTs, whereas in real life very few of them are. Now the line is composed of about half 180s, a handful of 'Networkers' (like the one at Pangbourne above), and just one HST. Luckily they can all keep to the same timetable. I plan to introduce more of this variation in stock on suitable routes -- two examples are the occasional HST on CrossCountry routes, and the occasional loco-hauled service on the Chiltern main line.
Paddington to Bedwyn services are also now operated by Networkers, as (I think) in real life, rather than HSTs. Finally, all Networker-operated services now run as 3-car, rather than 6-car.
The revised HST takes up seven station tiles (when formed with eight passenger cars). The increase in "footprint" is the main obstacle to rolling out the "length=10" change to all stock. In this case, I was just about able to make room for a seven-tile platform at Paddington. This won't be so easy everywhere. For instance, I'm less sure that I'll be able to convert the SWT 444s to this new scale, since they will also require seven tiles for ten-car operation, and I can see this being a problem in some places. But we'll see.
