Rails on Planet Hex

Back in October I completed my Doctor Who micro-diorama on a hexagonal base measuring 7cm between each set of flat edges in order to fit within my display cabinet. A second base was cut from MDF as a "just in case" and whilst not used at the time it was actively considered for a Christmas scene and a suitable tree was even sourced. 

I had wondered for a while whether such a tiny base could accommodate any meaningful railway scene so in an odd moment or two I created almost the seasonal opposite of what was previously intended!

Construction is very similar to the methods used for the Tardis Scene the track went in first with 5mm foam core board segments either side that were carved to shape and then blended in with modelling clay. Track was weathered and ballasted, before a base surface texture mix was added followed by the same fine sand used on Shifting Sands. This was laid liberally over a layer of PVA, allowing it to overflow into the ballasted areas and then matt medium used to fix the layer for a natural look.

The base will just accommodate a small O9 loco, in this case the recently completed Motor Rail. The grasses are a mixture of Silfor tufts and Peco 10mm grasses, cut from strips as I did not have suitable tufts in stock. A little pruning with nail scissors increased the variety of lengths. All grasses were dry-brushed with a light green/grey acrylic paint which really helps take off any sheen. Finally MIG 'Beach Sand' weathering powder was used over the sand to lighten it and add variety to the colouring.

I'm really pleased with the result, there may be more scenic modelling to come soon...

422 Variations

Work on the 422 Modelmaking wagons continues. Having proved the concept to modify the axleboxes on the spare chassis, I have now modified both of the other chassis castings. In this view one is lined  up with a modified Peco chassis, and the sad remains of it's old body! The Peco chassis has been modified to accept the Mathieson 7mm wheelsets which required removal of all brake gear, and opening out the holes above each wheel to be fully rectangular. 

 

The modified 422 chassis has the axleboxes modified and if you look carefully in the centre of the tubes you can see the dodge I have employed to mimic the end of the axle. This uses a moulding from the Dapol railbus kit, cutting the round mouldings off the parts on the left of the sprue, reducing some in size a little to match the others. By drilling out the back of the tubes I could insert this and give the impression of an axle in the bearing.

 

Once the axleboxes were sorted out I glued the chassis to the bodies using Araldite, clamping where necessary to bring everything together with minimal gaps. I then opted to add some extra details in further individualise the models, adding some basic hinge details to the drop-side wagon and handles either end of the one-plank to allow the body to be removed Heywood-style.

A closer view of the handles, formed from 0.7mm brass wire. With the 0.7mm drill bit out I also drilled the bufferbeams to accommodate Grandt Line 1 1/2" NBW mouldings to break up the plain surface. Not visible are the two holes drilled underneath the chassis on the centreline at each end, 1.5mm apart, ready to secure Greenwich couplers in due course.

Both wagons are now cleaned up and ready to paint. The third chassis with the experimental (and indeed removed) axleboxes is being brought into line detail wise and a body is planned using some recycled material...

422 Wagonry in Resin

Having completed the Motor Rail/Simplex and with my mind telling me it was an 18" gauge loco rather than 15" gauge, I felt the need for the some suitable rolling stock for it to work with. Having followed the development of the 422 Modelmaking range of resin cast O9 wagons, Narrow Gauge North provided the first opportunity to see them in the resin, so to speak...  

I chose to sample one of the 1-plank fixed plank and a 2-plank dropside variations along with a few spare bits and pieces. The castings are relatively clean, requiring some fettling of flash around the bottom edge of the bodies and top of the chassis, and a quick sand on flat 400 grit wet and dry paper to level off these surfaces ready for assembly. After cleaning up the castings I posed them for the camera.

The chassis are designed to sit on Peco N gauge 10ft chassis with their buffers removed and weight still attached above, so a suitable example was purloined from the stores. Bearing in mind this is sat on the flanges and not on rails, the axleboxes are quite low to the ground and do seem a little large compared to the wheels (which admittedly you cannot really see!).

I appreciate the need to hide the Peco undergubbins but I decided that this area required a little further consideration. I did purchase a spare chassis and also a version without axleboxes. This has allowed me some room for experimentation, the earliest of which was to see if the axleboxes could be cut off an shortened in height, not a resounding success... On the opposite side of the chassis I squared off the bottom of the axleboxes with the idea a square cover could be added along the lines of the Heywood or Theakston axleboxes. This is the state of play on the right of the photo.

Some further thought produced the option on the left. By carefully drilling with a 3mm drill bit and some gentle opening out with a round file I could insert a length of Evergreen 3.2mm tube. The remains of the cast axlebox from the halfway point of the tube downwards was removed, co-incidentally lining up with the triangular support gusset either side. The hole needs filling with a slightly protruding length of rod to resemble the axle end.

I will probably opt for this option as the end result will not be too dissimilar to the Black Dog Mining style axleboxes on other O9 models. It also has a clear lineage to the originals in terms of shape etc.
