Has this actually been done for locos? A practical disadvantage, might be the
risk of damage due to unbalanced firing ie too much fire while too little
throttle. The sluggishness of a conventional [steel wheeled] pressure cooker,

Comparable problems in stationary boilers. If you use the exhaust to preheat
something, then this must impede the exhaust flow and increase the back
pressure.
Consequently the engine delivers less HP, because it is not the stop valve
pressure but the difference between SV pressure and exhaust pressure, that
defines the work done by the pistons.
Hence racing cars may have "open exhausts" ie no muffler, hence little or no
back pressure to subtract from the pistons' output. Noisy!

Write your reply.

assistant: Torque or pulling power is dependent on Amps (after deleting all the
other, lesser factors)
Horse power is torque multiplied by RPM (times a constant)
At starting/stall the electric motor produces maximum torque but zero
horsepower. The torque will steadily drop as revs increase, while
horsepower will increase to the designed maximum at say, 75% maximum
revs, and then steadily decrease.
Steam locos have a similar torque and horsepower curve but typically
maximum horse power is at about 33% of maximum speed.
A Diesel motor has no torque at zero rpm. In fact it must reach about
half maximum speed before usable torque is produced, hence the need for
an electric or hydraulic transmission.
On English steam locos, there is generally little in the way of
equalization provided. The loading of each axle is achieved by
adjusting the spring hangers, shackles or whatever adjustment was provided.
An advantage of this system is that the unbalanced connecting rod forces
are not transfered to the other axles. With the more even English trackwork,
the advantages of equalization were not so great.
Generally the locos exported from Britain followed British practice, so
Australia, New Zealand, South Africa etc. ended up with non-equalised
locos at times.

10 degrees, 6 degrees etc. As the curves in question definitely made a
reater
angle than the quoted figures, being more like 90 degrees and 135 degrees of
turn, I guess that this is a local nonclaimiture for a particular radius?
My guess is that it relates to an angle of turn over a given length.
If so how long is your piece of string?
Otherwise, how do those of us who are not in the know to recalculate these
numbers to units we can understand?

assistant: Measuring curves in degrees is standard practice
on North American railways.  It is confusing even to North
American railfans, and discussions of the system take place
every so often on the Internet rail-related lists
explaining how it works.
        As I recall, you have the right idea, but I don't
recall how long the string is.  And the more technical
discussions get into where you measure from--which rail,
which face of the rail, the center line, or what.

Ahhhhh... hate to butt in, but I am a volunteer with a steam preservation
trust called "Mainline Steam" here in New Zealand.
All our locos are sprung in some manner or form.... in fact we are just
replacing the springs on a 2-8-2.
You think about the riding characteristics of 8 wheels coupled, tottering
along at 60mph unsprung... the drivers would develop serious faults such as
cracking and vibration would lead to other egine faults (frame and brass
problems??).
Granted they are rather stiff... some of our track isnt the best and there is
a little hump going into one of our shed roads, which is very noticable
(see-saw effect) when we drive over it.
We also have a diesel (Drewry built 0-6-0) with coupled wheels, and the
pings
are on the  outside of the frame....
i dunno..........

assistant: Another of life's little conundrums!!
a
We're back to the same problem you had with your washing!
The energy savings can be appreciable in recovering the waste heat, and it
is relatively simple to provide a flap to exhaust to the open air when full
power is needed.
The potential big saving with condensing on a steam loco is to not need such
a big water cart, which needs hauling around.
Not quite! The open exhausts are very carefully designed to provide
back-pressure at operating speeds. Because the inlet and exhaust valves are
open
at the same time, the design trick is to get all the burnt gasses out, but
ot
to loose too much intake air and unburnt fuel.
The "open" exhausts only provide the required back pressure over a very small
rev range, hence the funny sounds from a racing engine at idle.
