don clarke has had an excellent career and thoroughly deserves a happy retirement,its truly great to know that nine elms drivers are still doing us proud.
I,m an LMS driver (rtd) and prefer LMS locos, but diving "clan line" somehow used to lift my spirits! storming through stainforth cutting in the dales, most engines did a slip or two, but this loco never misbehaved,john.
*The Clan Line locomotive have some controls* that I don't immediately recognize. Apparently every railway in Britain had different specifications for the throttles. I didn't expect to see much of the reverser/cut-off, which is low ahead of the driver but probably uses a worm-and-wheel for better precision than the detented Johnson bars on all United States-built steam. Are the water injectors and vacuum-brake regulators on levers, as appears the case from the vid?
Give credit to the people who planned and designed these steam giants. Even in their current advanced development stages they are dangerous and need constant attention and adjustment. Seems like controlling a herd of elephants with a stick. Gotta admire steam power for what it can do and what it takes to control it.
I've posed this question elsewhere, but why does it appear such hard work to pull the regulator lever to increase power/speed? Secondly. what is the function of the valve control I saw Driver Clarke turning with his right hand @ 0:39?
The regulator I'm not sure about ( the handle is probably a bit stiff!) but the valve control you are talking about adjusts the cutoff of the steam engine. It works the same as gears in a car do ( lower gear for hills, higher gear for speed) Hope this helps!
+hughvane The regulator is hard to pull because of the linkages. Most domes you see on locomotives are either where the sand is housed, or where the steam accumulates. There are pipes inside/under the dome that lead to the cylinders, these pipes have valves on them which control the flow of the steam. In a locomotive such as this they're under about 220psi of pressure. Which means that to have control of the steam going to the cylinders, the valves in the pipes need to be able to resist this pressure so they don't open themselves and lead to loss of control. The pressure acting on them means they are hard to move, as well as the safety feature that prevents them from being blown open. The handle the driver turns is the cutoff. The cutoff is what is used to determine how long the steam remains in the cylinders by adjusting the valve timings. The longer the valve is open for, the more steam can enter and expand. Driving a steam locomotive is full of constant adjustments of the regulator (the amount of steam you're injecting into the cylinders) and the cutoff (the amount of time the steam acts in the cylinder)
@@_Anato_ Wow! Fantastic information. I have wanted to ask about the regulator many times,but,didn't want to come across as a dumb,dumb,and get not so nice comments from one or, two intolerant smarties. I was taken on the foot plate {Stationary} with my Granddad just for a look on one of the old steam coal locos pulling up the hill towards Caledonia. I never forgot the smell,and all the controls. It has stayed with me all those years.

Good video, i like these rebuilt west country loco's they are very powerful and look great.
Merchant Navy ;).
Robert Tarling Ditto the West Countries!!
In the presence of Greatness!

nice one don, hope you enjoy your retirement. George ventham.

... nice footplate video
Very good.
Does show clearly the limited view for steam drivers and the difficulties this must cause.
when firing a steam engine right or left handed you should always fire it on the opposite side to the driver for obvious reasons.
