@spoofa20 The New South Wales Railways green 3801, and the Victorian Railways R class were allowed 70 miles per hour (MPH) but could go faster than that and sometimes did. The Victorian D3639 was similarly limited to 60 MPH. The K class loco, having smaller driving wheels, was run at 50 MPH on later passenger trains but was originally built for service on goods trains. They originally had maximum speeds of 45 MPH on goods trains on main lines; but lower limits on most (lighter) branch lines.
@mistersmith6000 The steam exaust from the cylinders, is blasted up the chimney which creates a draught through the boiler tubes and draws the fire hotter the harder the engine is working. The draught or most of it is drawn from beneath the fire through the grates. Steam mixed with the smoke causes it to be grey but it depends too on the way the engine is fired. The green one is hand fired while the R has a mechanical stoker which makes a difference too. Smoke from 38s was always impressive.
@trainguyrocks - The R is designed as a fast passenger train engine whereas the K is basically a slower goods engine with comparatively smaller wheels so the speed of the train with the K in it, was limited to the allowed speed of the K; but the trains were all speeding up and slowing down during the trip so that passengers could all get a good look at them.
Can I ask what the maximum speeds of these locomotives are?

@reidgck thank you -I was sure some steam locos could pass the 100MPH mark if they were allowed to.

The green one doesn't blow black smoke? Why is the smoke colour so different?

Thanks for loading this awesome material from '88. Looking at it, I wished that I'd spent the money and gone on the trip :)

@bronski88 Would be good to see such again. It's not an impossibility should support come from the right places and if there are enough passengers.

That R class is fast it faster that a d3 class and a k class pulling a traintogether !
