Having made a few posts about the general arrangement and a few details about Swan Hill, I'm just getting around to signalling so it might be a good moment to post the provisional signal diagram "for comment and suggestions" and see what comes up!
Swan Hill is GWR and dates to 1927 (or thereabouts). The track layout is loosely based on a reduced version of Uxbridge Vine Street with the goods yard accessed on a reversal (from road No 3) similar to the arrangement at Windsor central s
I've always rather liked the rivetted plate bridges which are commonplace all over the railway system and which are the subject of this post. I've included a couple of GWR bridges in the Bristol area for reference and from which the particular shape of section supporting the raised steel parapet is drawn (Google "fair use" credit): it may be particular to GWR plate bridges as I haven't noticed it elsewhere. For general reference on steelwork (and in particular on rivetted structural sections) D
I might do several posts in the next couple of days to summarise what I've been doing - I've been busy but there doesn't seem to be much to show for it! Nevertheless, I've tried to take some pictures along the way - this post is about buffers.
There are five end stops required at Swan Hill so it's worth making up a tool for bending rail and a jig for assembly. First up is the tool for bending rail on its wider axis so that it doesn't distort at the bend, followed by a (scruffy lookin
The fish platform (which includes all fresh produce) at Swan Hill
Fish platform at Swan Hill: it sits on a bridge over a road junction beneath, so timber built. A second timber built platform is under construction: same set of details based on a timber platform at Methyr Tydfil but slightly different dimensions to the fish platform as it's passenger, not goods, so a nominal 3' 0" over the rails rather than a couple of inches higher for goods.

The system devised to motorise the 11 points on Swan Hill may be of interest to others. I wanted a simpl(ish) mechanism using servos controlled from a Megapoints board and toggle switches – all new to me – to drive a protypical angle crank (rather than a slot in the baseboard type arrangement).
The photos show servos mounted under the baseboard in a piece of aluminium angle slotted to carry the servo. The servo drives a short length of 2mm steel rod fitted with spade connectors each
I had hoped to show more progress at Swan Hill by now but in spite of hours put in, output looks a bit thin. There's been plenty of drawing (it's warmer indoors at the computer) - part of the current fabrication drawing is shown below together with a few pics of the work-in-progress viaduct and bridge abutment. The abutment face is slotted for square section rainwater DPs but the bearing shelf is incomplete until the bridge itself is made and can be fitted to get the height exact. Unusually,
No great excitement but the last section of trackwork for part one at Swan Hill was completed over the weekend (including the bare bones of the last base framework required). The Slater's all 3rd coach standing in the down siding is also now complete (except for one or two brass fittings for the ends) and a 1900 vintage rivetted steel plate bridge beam installed on its padstones over one of the lanes under the viaduct. Work on the viaduct walls and the shops/warehouses underneath will be the f
Swan Hill is the terminus of a short, double track commuter branch off the GWR in the vicinity of Langley, imagined/modelled in 7mm. The last mile or so of the branch, including Swan Hill station, is carried on viaduct – Windsor comes to mind. The track plan owes something to Uxbridge Vine Street but with only a down siding for reversing into a goods yard (as per Windsor but off scene) and an up siding, shunting spur and dock. There is a single passenger platform serving arrival and departure ro
On a cold and damp Saturday and having viewed with huge interest various blogs on RMWeb over the last year or two and having revived a family tradition of building model railways, I decided it was high time to dip a toe in the water and share - with trepidation - the state of play on Swan Hill, a GWR terminus station somewhere in the Thames Valley and sometime in the 1920s.
The photo shows the extent of trackwork on Swan Hill as of about three months ago. If the start of this blog
