Ballasting isn’t my favourite modelling activity, so ballasting Upwell Drove was seen as a necessary stage in construction, rather than an eagerly anticipated bit of model making. I spent a lot of time looking at pictures of the Wisbech and Upwell, and one of my aims in the model is to show some of the different types of trackwork found on the prototype. So we have the “reserved” track as the line enters the station, which is conventionally ballasted and laid, Then there is a section of tramway track, with the rails level with the road surface. Finally in the station some of the ballast is just cinders, and the track is set in the surface.
The track was laid, and painted with Railmatch sleeper grime before ballasting. The sides of the rails and chairs were painted Tamiya matt dark brown. The sleepers were then dry brushed with various shades of Tamiya grey and earth.
The ballast for the model is made by mixing chinchilla grit with fine ash, about 50/50. The ash has the effect of darkening the chinchilla grit slightly, and adding additional variation to the colour. Looking at photographs of the W&U and other secondary lines, I was struck by the quite “open” appearance of the bullhead track, with a clear separation showing between the top of the ballast and the bottom of the rail. Part of the solution was not to use too much ballast, but I also found the cutting away the web between the sleepers after the track was laid greatly improved the appearance.
The ballast itself was spread dry between the rails. Before pouring out the ballast (I did a bit at a time from a teaspoon), I laid a strip of masking tape about 1mm from the ends of the sleepers, which limited the extent of the granite ballast. Once spread out, the ballast was sprayed with water with a couple of drops of washing up liquid in it. WW scenics pre-mixed ballast glue was then poured over and allowed to dry.
Once dry, the sides of the rails were touched up with Tamiya flat brown XF10. The rails and chairs were then given a wash of a dark grey colour, made from various mixes of Tamiya NATO black, dark grey, khaki drab and dark earth. The chairs were then highlighted by lightly dry brushing with Humbrol acrylic brick red. I then applied some rust coloured weathering powders to the rails and chairs. I mixed a small amount of the weathering powder with white spirit, and brushed this on to the sides of the rails. The white spirit evaporates, leaving the weathering powder in place. The chairs were then lightly brushed with a lighter rust shade.
The final step was to lightly spray it all with Humbrol matt acrylic spray varnish, This kills the sheen left by the WW scenics glue, fixes the weathering powder in place, and appears to enhance the contrast between the sleepers and ballast.
There are some variations in the track treatment. Some of the ballast is just cinders, and I spent some time thinking of how to replicate this. I was quite taken by Chris Nevard’s various writing on the subject, and the effect he achieved sing Das modelling clay, spread round the sleepers. I have used this method under the moving parts of turnouts, and at the baseboard joint. Once dry, the Das is painted with an earth colour mixed from various emulsion match pots (I used the Valspar range in B&Q), and the rails treated as described above. The finer cinders ballast outside the main ballast on the reserved track was made by sprinkling fine ash on wet PVA. Finally, the grassy areas around the track were built up with various length of static grass, starting with a base layer of 2mm fibres, and building up additional layers of 4, 6 and 10mm fibres. This is still a bit of a work on progress, as too much static grass can interfere with running, and I need to strike a balance between operability and appearance.
I need to complete the ballasting of the sidings in the yard, and then I shall start work on the grassy areas and road surfaces in the yard.
Cheers for now
