23:50 - May 2014 Bonus 2 - Extreme weathering, part 4 - Locos (2014)

In this four-part Backshop Clinic, we follow Ralph Renzetti's techniques for weathering model railroad equipment.  In this segment Ralph finishes the process of applying some extreme weathering to a locomotive.


The extreme weathering series has been excellent.  I now understand how to create more realistic weathering for my models.  I hope there is at least one more video highlighting weathering steam locomotives.

Kudos to Ralph for sharing these techniques.  Most of the fine scale weathering experts I have encountered treat "their" techniques like trade secrets.  I am most appreciative that Ralph shared his knowledge with us.

Ralph, is that cradle you're using a home made deal or manufactured one you modified?  That's genious!  Great set of clinics!

I'm in the process of developing a clinic on weathering Steam Locos. Quite a few years ago MR magazine did an article on weathering steam locos which still applies today using 'V' shaped templates and an airbrush.

Unfortunately there are not too many prototype photos around so you have to take what you can when you can get it. Up here in Canada there are usually guys at the local train shows that sell black and white photos. A lot of times the weathering on a steam engines is the build-up of calcium from bleed off valves and piping leaks. One of the other things to concider, just like diesel, is the area of the country that the engine operates in that will determine the colour of the dust on the lower half of the engine.

I can't stress enough the importance of using proto photos to copy from. If you try to improvise from your head or your minds eye, chances are very good that you will overdo it, which by the way is the way I started out. It wasn't until I became a member of a weathering forum called, 'Model Trains Weathered'(MTW), which closed down about 4-5 years ago, that I sort of got my groove on. I don't know about you but I have always beenthe type to learned by the 'Show Me Method' (hands on sort of deal). The guys there were willing to share once they got to know you and you asked the right questions.

The guys at MTW were willing to share and I'm paying it forward. I would say 99% of us are all in this hobby to have fun and I feel you can't have fun keeping everthing to yourself. I had a blast doing these videos and I guess my ultimate goal is to get one more shinny new toy off the rails and into the weathering shop, if for nothing else, a coat of Dulcoat.

Thanks for the kind words and the support.

The craddle that I'm using in the video is home made only because my commercially bought craddle is missing in action. It's in my layout room somewhere but have not been able to locate it since mid February.

I made this one with some modifications that I wished were on the commercial one, like an area to put the chassis while working on the shell. This craddle it made up from some closed cell foam packing material from an electronic purchase we made at Christmas.


Thanks a lot Ralph. Greetings from Argentina.


Fantastic! These clinics are exactly what I have been looking for, methods explained well and the products use so that I can confidently attempt the same process with low risk of ruining a locomotive.



Thank you for this series. I learned quite a bit and look forward to starting on my fleet of cars and diesels. Is there a list of the products you use somewhere or can you provide one easily?

I have at he'd the series a few times and learn more each time.

I found AK Interactive material on Amazon, but found several sets that seem to mostly be for military model applications.  Do you use any of those sets or do you buy separate colors and if so, what are those colors?


Thanks again for a great set of clinics.



 How come I can´t se the Extreme weathering part 4  ???
