It might be a while off yet now that they've decided that it's going to be easier to repair the old boiler than modify the new one. What a fiasco that was...

[Fatso]

Used to fire then eventually drive 3801 and a lot of others when I was a young bloke , hard work sometimes especially from Picton to Bargo with freight or on the Newcastle Flyer flat out Hi-wheel .


But on reflection it was great days , better than a real Job !!!!

You must have some great memories.
Growing up in England, in the fifties, it was many boys' dream to be a "Train Driver" (Steam of course!), & I lived in Manchester just around the corner (literally) from the HUGE Beyer Peacock works, which manufactured over 8800 Steam locos, quite a few of which ended up on Aussie railways. And my Dad's relatives, the "Budenbergs", manufactured steam pressure guages, many of which I've seen in Aussie locos.

Please explain?:D

[Fatso]

Passenger trains where reffered too as hi-wheel , as most passenger locos like the 38 class and 36 class had driving wheels of around 6' 4" in height for speed and freight locos had much smaller wheels for better traction , that's why locos like 38 class were a bugger of a job pulling freight trains , from memory 38/36 class loco,s could only pull about 565 tons to Goulburn . Not sure where the term originated but there you go .

Have some great memories both good and bad mostly good though , used to have great fun when I first started as shop boy in the Chullora workshops at 15 yrs of age , and at 17 was excepted as a Trainee Engineman ( oops, person ) at Enfield . There is something alive in Steam Engines, I thought so anyway , we had the 60 class Bayer Garret in NSW great loco as long as you knew how to fire them , unforgiving if you didn't .

When I was at both Eveleigh and Delec, long after steam had finished, there were a few regular tabled high speed goods trains that were also referred to as High Wheelers

Perishable goods trains had that label , mostly were pulled by pax loco,s for speed , thay actualy got priority over pax trains sometimes .

As a current Eveleigh driver, we still use the term "high wheeler" for express services that make few stops.

Thanks for the origination of the label. I could never see what the label "High Wheeler" had to do with a fast goods train.

I wonder if it was gearing rather than traction?

Without putting to finer a point on it , yes .

[JDNSW]

Simply gearing. Two ways of looking at it - for high speed, you want to have the reciprocating mass (piston, con rod etc) changing direction as slowly as possible, since as the speed grows the stresses of accelerating and decelerating increase; so these have to be stronger, which means heavier, which means the stresses are higher - imposing a practical limit on the strokes per minute (you can shorten the strokes, but this reduces the available power for a given steam pressure and piston diameter). In the last quarter of the nineteenth century, many express locomotives had single driving axles with very large diameter wheels

For pulling power there are two factors at work. Smaller wheels (and more of them) allow heavier engine weight within limits of axle loading and length of rigid wheelbase, and the limit to tractive effort is a function of piston area, steam pressure, and the leverage between the crank and the wheel rim. How far out you can move the crank is again limited by needing to accelerate and decelerate the piston, plus the limits imposed by the need for track clearance. Piston diameter is limited by loading gauge, putting a limit on piston area, without increasing complexity.

There are a lot of factors that went into designing a steam locomotive, and most of them are compromises, so it comes as no surprise that a few designs were outstanding successes, a few others utter flops, and a lot were "so-so". A bit like cars or four wheel drives.

The 38 class has to be considered one of the outstanding successes.

My father-in-law was also a fireman on the 3801 when it was the Newcastle Flyer around the 1950's I think.
