A couple of dirty 45’s …

Hi all,

Recently, I decided to have a go at weathering a couple of my Auscision Models 45 class locomotives.

This all came about some time ago after I had opened up one of the models to determine what was going to be required to change the wheelsets to RP25/88.

A problem I found was that the half axles are shouldered, and would not have been easy to replace the wheelsets without drilling out bearings.  After a number of weeks just sitting on the workbench, and pondering the NMRA Fine:HO standards, I decided to leave the factory fitted RP25/110 wheelsets in place, as these will operate on the new standards.  Also, locomotive wheels are virtually hidden behind their sideframes, so the tyre tread width is not very noticeable.

So, having decided to keep the 110 wheels, and before putting the loco back together, I thought it was an ideal time to do some weathering.

The 45 class model comes apart relatively easily.  The couplers are removed, then the four screw retaining the one piece body which reveals the chassis and motor.

The sideframes are amazing pieces of engineering, resulting in a highly detailed copy of the prototype.  They also are very easily removed from the bogies.

The bogie keeper plate also unclips easily exposing the drivetrain.  The wheelsets were re-gauged to the new back-to-back measurement using a new gauge obtained from DCC Concepts.

The weathering process involves using artists’ acrylic crayons ground into a fine powder then sealed with isopropyl alcohol after each application.  The crayons are the Conte brand and were sourced from Art Scene.  The technique was shown to me by good friend and fellow weathering artist Aaron Denning.

The photo below shows a locomotive separated into its main components, ready to start the weathering process.

The chassis is then masked off to protect the electricals and motor.  The chassis and bogie sideframes are then painted with Krylon camouflage flat black and the body is sprayed with a matt clear coat.  I have used Tamiya flat clear.

The sideframes and chassis are then treated with various colours of the powdered crayons, working from photographs to get the desired result.

Again working from photographs, the body is treated in a similar manner.  An all over dusting is done to tone down the factory colour, then black is applied to the roof.  In the pictures below, 4507 has retained the crew and had the windows opened, as it will be a lead unit.  4531 has had the crew removed and windows left closed as it will be a trailing unit in a consist.  To do this, the cab needs to be removed and with a bit of delicate poking, pulling and pushing, slides right off the body.  This was actually done prior to hitting with the matt finish so the cab interior gets done.

 

The following shots show the two completed models.

 

The last picture shows the inspiration for 4531.

 

That’s two out of eight done!

 

Cheers.

  1. Ian, amazing work mate. They look superb and ready for some hard slogging. Is there anywhere on the web the pastel method is described? Thanks

    • Hi Daryl,

      Thanks for the kind words. Back in Dec 2014, I did a blog post about weathering the Chilcott’s Ck bridge girders. There was a link to a PDF of Aaron Denning’s technique used on an Austrains’ WHX wheat hopper. If you search my blog for “WHX”, you will find it.

      Cheers.

  2. Nice work Ian
    Just an observation
    But, its funny how the hobby has grow more demanding with the introduction of rip it out of the packet modelling.
    This must be what it was like to be an American modeller 40 years ago.
    The talk of correct positions for the drivers seat which is important now but even 12 months ago all we had was the AR one, which i didn’t lower myself to get or David Anderson,s 45 which was excellent but no talk about drivers position we where just happy to have something that we didn’t have to put together or fix.
    Can you do me a favour and get a depot plate on it, before you start on the drivers seat ?

  3. Hi Ian

    Just a couple of things & firstly now that I have seen the location of the driver in the model, & can see the fireman also on the other side, for me the fireman’s seat & location is right however, the drivers figure to me is too far forward, meaning the seat is also slight too far forward. The aspect that is normal, & I put myself as being average height, so when sitting in the drirvers seat, the backrest would be at the end of the control stand & the driver would be seated less upright & back more.

    I like the overall aspect of the weathering especiallly the smoothed in colouring tones, & I also love working with the artists pastels. I purchased some from China directly, also some from an Ausrtalian company who put out the Monte Marte range, which are very good.

    Thing to me though is most 45cl when they started to get the faded look, they also had a lot of oil leaks, this is an area where the flat pastels will not work, maybe on a base coating but they do not present the mid point shine that the sump oil from the stack produced, it lay on the footwalk & fan room area, & gathered a lot of dirt over the time as well.

    • Hi Col,

      Thanks for the comments. I sort of forgot about the driver position until after I had replaced the cab, so I won’t move the seat in 4507 but will on future ones.

      I’m hoping I got the oil leaks correct, as I was working off photos, but the lighting in my photos probably doesn’t show it correctly. The Tamiya clear Smoke colour I used does in fact produce a ‘sheen’.

  4. Hi Ian.Regarding the 110 wheels on the latest generation of diesels I know it is very frustrating to want to change them to 88’s or finer but as I found out myself that sometimes it’s better to leave what is in place when the loco runs well. Oh yes superb weathering.Regards Peter
