You 've seen some of my aircraft and ships, but this is a bit out of the ordinary for me. Richard Trevithicks "Penydarren" Locomotive from 1804. The model is approx 1/38 scale. It was designed as an educational model but after checking a few reference photos I've added some more detailing. (steam relief valve, pressure guage, contol rods, side rails on the tender) Paintwork is a matt black base with various metal shades and graphite from an HB pencil! All the external mechanical parts actually work, the only thing it can't do is produce steam! As usual comments welcome.

Kind of makes me wonder where the fireman stands to stoke the boiler.  At the speeds those things could go maybe he walked alongside.  Lots of machinery to get tangled up in there too.  Your Health and Safety guys would have a woolly-worm over that one.

The fireman stood on the platform of the tender from what i've seen on photos of the real one. I've also seen photos of the tender attached at the other end with the firebox accessed at that end. It is something of a mystery. The replica that runs has the tender and the firebox at the other end so that the protruding pistons operate away from the crew. It only moved at about 5mph max so presumably it could be stopped to shovel more coal in when in use. The basic engine was in fact a normally fixed base boiler mounted on wheels for the purposes of the experiment. As you say, the thing looks like a H&S nightmare now, but back then of course was as cutting edge as the TGV!

What fascinates me about these primitive machines is how they were literally the engines of change in human history, from an agricultural to an industrial society in such a short space of time. The steam engine changed the social, political, technological and geographical landscape of the globe. And all because some bright spark watched a kettle boil. He was probably just making a cup of tea.

Amazing! Eons ago, in my school years, one of my classmates had a working steam engine (about 25-30 cm long). It was static, you had to put boiled water in it and after a minute or two it just started spin the wheels like an old locomotive. Even had a working whistle. When i saw the pictures, just popped in my mind how much fun we had with the little machine. Good stuff, Alan.

Terrific work Alan. Love those old machines too. I have drawn many steam locomotives for tshirts in the past...even a donkey engine..essentially a stationary version of what you got there designed to haul logs up slopes and onto railcars...pulled by steam locomotives.

 

Agreed bout this being a super finish job.

 

thanks for sharing it.

This is a working replica, you'll notice that it has a different layout to the original inasmuch that the chlinder and piston is at the other end of the boiler away from the crew. The principle however is the same.

This replica however is nearer to the one i've built.

Heck of a piece of equipment and excellently modeled Alan. :thum::cool: Wouldn't mind seeing one work in the RW. :)

 

A shame the model wasn't on rails instead of those brown waves.

The brown "waves" were actually iron rails made in short sections. they were basically the same things used on the Donkey trackways used at the coal mines. The long lengths of steel rail had yet to be invented.
