Hi all
Is there a steam locomotive on the market that can be
kitbashed into some thing that looks close to a SAR steam loco.
Any and all help greatly appreciatded

Webb's steam engines - the 500, 600 and 700 classes - were based on USRA Light Mountain, Light Pacific and Light Mikado designs respectively. The biggest changes were to the top lines of the locos: the funnels, domes and cabin roofs were lowered to fit the SAR loading gauge, which was extended to allow for them.

So credible SAR steam locos can be built from models of the above US prototypes.

The closest SAR locomotive out of a box would have to be the Mehanotechnica light Pacific, these have have been sold by various companies over the years including, AHM/IHC, Lifelike etc. The boiler and cab need a fair bit of work but the wheelbase and drivers are almost spot on to a 600 steamer though, many have been converted to 600 class steam locomotives in SA. The tender needs a lot of work as well.

It can be as simple as you want it really, you can go the whole way and get it near enough or just do some things and a quick repaint. It is up to you.

As this body works for a 600 steam locomotive, it is also offered as Mikado in these ranges as well, so it could be assumed that you might be able to get a 700 class type loco out of one, either a 700 class, 710 class or a 740 class loco. I have never done one of these locomotives though, I have done a 600 though. This would probably need a new body for the locomotive made.

Note that the valve gear on the pacific at least is Baker valve gear which was only used on one class of SAR locomotives the 620 class, so it might be able to with a lot of rebuilding to get a 620class out of the pacific as well, you would need to build a complete body for the locomotive though from scratch. I have done one, a long time ago and it will pass at a glance for one, just don't count rivets though.

All the above will only be near enough's though, the 600 class being the closest to scale of any of them.

I used some PVC plumbing pipe of near enough diameter as a starting point for the boilers though, this solves a lot of problems and is easy to work as well.

Once I pondered over the possibility of modifying a Thomas Train to an F Class tank, but you would have to be confident extending the boiler and tanks and you would have to add bogies (but not the yucky sort!). I didn't bother as I don't have enough modelling skills to do a good job of it.

520 class also be out soon as well

Perhaps a better question might be "what SAR steam do you desire?"

BGM have produced kits for:
700/710/740 class and T class. BGM are also promising the 500-class.

SARModelco have produced the F class. You may be able to get a kit from them? It was a limited run of about 200.

Rocky River have produced akit of the "Big Mikado", the 720 class (but this is really a Berkshire wheel arrangement! Very Happy ) and they have the mighty 520-class in production. Sometime in the future they plan to do the 620. I believe that the 600 is planned as well.

Another individual is currently producing the Rx class.

Lastly, and this is in the realm of the kitbash... Bergs make the NSW F351 class 2-4-0 loco. This is a very easy conversion to the SAR P class. They are very similar locos made by the same company around the same time. Aside from the cab, most differences are relatively superficial.

Good luck!

Thank you all for your replies.

This is a complete myth.
The SAR locomotives were much lighter and except for the 600, were much smaller than the USRA locomotives. The reason the 600 is close is that it was slightly bigger than the USRA light Pacific and had the same driving wheel size. The Light Mikado was similar in dimensions to the 500 class rather than the 700 class...

500 class Cylinders 26” x 28” driving wheels 5’3” wheelbase 17’

Lt Mountain Cylinders 27” x 30” driving wheels 5’9” wheelbase 18’3”

600 class Cylinders 24” x 28” driving wheels 6’3” wheelbase 13’8”

Lt Pacific Cylinders 25” x 28” driving wheels 6’3” wheelbase 13’0”

700 class Cylinders 22” x 28” driving wheels 4’9” wheelbase 15’6”

Lt Mikado Cylinders 26” x 30” driving wheels 5’3” wheelbase 16’9”

In addition, the boilers on the USRA locomotives are distinctly tapered while those on the SAR locomotives were parallel or almost so...
Hence David Peters' use of PVC pipe...

Many years ago, the Tyco, later Mantua, Mikado could be modified into a reasonable facsimile of a 720 class even including the tender. You needed to find or scratchbuild a two axle trailing truck, and alter the cab from vertical to sloping front plate.

In about 1964 I upset a well known SAR modeller of the period by identifying his 720 class as a modified Tyco locomotive. These were substantial die cast models and ran well.

What are the differences between a USRA light mountain and a heavy mountain locomotive.

If someone can offer some technical help I'm interested in kitbashing a SAR 500 class steam locomotive but want to find out which base model is better to use either light or heavy mountain?
Thanks

Just a friendly tip, try not to bring up two year old threads, as it is generally frowned upon.

Anyway, the Model Design Studio is making a body kit for the 500 class that fits over the mechanism of the Bachmann Spectrum USRA Light/Heavy Mountain. Here is a link to their website: http://www.modeldesignstudio.com.au/500_class.html.

The last I heard was that this kit would be released at the MRSAC Convention in August, but you may want to contact Nigel to see if this is still the case.

This will probably be much easier than kitbashing the URSA Mountain into a 'near-enough' lookalike.

Hope this helps,

Matt

Ok this is not for the faint hearted but a C30 tank locomotive can be hacked around to get a look alike F class loco out of it. Either a kit or brass, I did a brass modification years back and from a metre away you get it something close to it.

Also the same goes for a C30T tender locomotive it can be made to look something like a Rx steam loco with some minor modifications done to it. You can use the 6 wheeled tender that comes with it or build a bogie one for it. There were several tender types used behind Rx locomotives.

For a P class other than using the Bergs F351 kit an Electrotren 2-4-0 loco with a bit of work will pass for a P class, these are not currently available new though but they are pretty robust so you might be able to get one secondhand they could also be used to make a NSWGR F351 too if you wanted to.

Article in the January/February 1979 issue of AMRM about converting a USRA Light Pacific into an SAR 600 - I used that article to build my 600 - 609 and I think I did a better job!
