Nice, i believe you should use oily rags? Plenty of those with owning
an LR then!

yep. I think people may have overlooked the pi in there.

cooo, shiny. Coal fired, I assume? must have a fair-sized grate. The ones
I used to play with were a lot smaller.

though Alan George had a cab by the time I was involved. Not sure why the
rolling stock pictures are so out of date, mind. I suspect the colour
picture top right of the 2 steam locos is one I took...

Alan George is quite a challenge to fire, though - grate is 2 square feet.
By comparison, Sgt. Murphy is a doddle.

She is indeed coal fired although many of that class were converted to
oil over the years they were in service.

All nice looking - I'll have to visit one day.

Just little uns then Austin. Worst piece about having to fire 1250 is
that the first scheduled service is at 8am so it's a 3am start.

Yikes. There's no such time...

'Snot too bad. Go out the evening before and set and light a fire, then
fire the bbq. Have me supper, give 1250 another prod and a bit of coal,
attack the bottle of scotch, then kip in the depot. Then an early start
doing the hard work of making a real fire and getting steam up whilst my
father-in-law (who's supposed to be doing the work) makes tea and cooks
a decent breakfast (bacon, eggs, hash browns, beans, and whatever else
her indoors has seen fit to provide). It's all worthwhile when you pull
out of the depot into a perfect morning and trundle off up the line to
the station in the sunrise.

Anyways, as I'm not suitably qualified to drive trains it's the only
time I'm allowed to so that's a bit of an incentive for the early
starts. As is the thought that using the whistle at level crossings at
7am is signalling the start of another Sunday for all those living
within a couple of miles.

Yeah, there's a certain magic about the moment they come alive, too - the
point where the blower suddenly starts working (tend to leave it turned on a
bit in anticipation, I assume the same on bigger ones) and suddenly the
thing's not just a lump of metal with a smoky fire in it but a living
creature. I'll have to find another driver for my school work part-time
next year, and see if I can get back into fireman training. One of the
local railways (Gwili) is standard gauge and more to the point has full
signalling, it is in theory possible to get a genuine steam driver's ticket
by training there. But fireman is a good start... although I guess it's
harder work on a big'un than the little 2ft gauge ones, although the little
'uns keep you on the ball 'cos everything happens so quickly. Used to get
the model engineer brigade sometimes, the sort who have 7" gauge live steam
- they reckoned firing Alan George with his 2 sq.ft. of grate was a piece of
****...

ah, I was wondering about the scotch. No booze 8 hours before driving, and
24 hours is better after a session in this country, like the airline pilots
and for similar reasons.

We tend to use a bit of compressed air in the smokestack to get a draft
going - otherwise the cab beomes a bit untenable (as does the entire
engine depot).

The only problem with a big'un is the sheer amount of coal consumed -
it's a very busy job keeping up with it when it's doing a lot of work.
So not too much of a problem just trundling around on the usual branch
line, but a huge amount of work when fully loaded and at speed out on
the main line.

I'm aiming for my fireman's ticket followed by my driver's ticket. All
the old boys who have steam qualifications are slowly passing away so
they need a few more of us slightly younger chaps to learn the art.

thought it might have been. The loco has an odd set of proportions compared
to "standard gauge" ones. same as ZA, I believe.
