Bristol Barrow Road - DCC Wiring - More progress

Having completed fitting all the droppers on the current scenic boards - roundhouse excluded - I have made a start on adding the BUS bars to the layout. I have decided to split the scenic section of the layout into a number of power districts or Zones as follows; Zone 1 - Up Main Zone 2 - Down Main Zone 3 - Turnouts Group 1 Zone 4 - Turnouts Group 2 Zone 5 - Loco Shed Sidings Zone 6 - Loco Shed coal/ash area Zone 7 - Loco Shed rear sidings Zone 8 - Loco Shed Turntable & Roundhouse si

Bristol Barrow Road - DCC Wiring

It is a while ago since I did any wiring on the layout when the UP and DOWN main lines were partially completed and wired with their own BUS bars and droppers. I decided it was time to get on with some more wiring and started making more droppers out of 1/0.6 wire, these being soldered onto double ended tags which can the be fixed to the underside of the boards. Over 200 of these were made up in preparation for the task. The single core wire is easier to push through the 1.3mm holes drilled th

Bristol Barrow Road - Days Road Bridge

Having settled into the new large shed I have given some thought to extending the layout into a continuous run with a long fiddle yard down one side of the building with the layout along the other. With this in mind I need scenic breaks at each end of the layout. At the north end the break will be the road bridge at Lawrence Hill north of the Junction signal box, whilst at the south - Temple Meads - end it will be Days Road Bridge. For those of a certain age this will evoke memories of climbing

BRISTOL BARROW ROAD - The Engine Shed

It has been a while since my last post this being due to a move of house last year and the consequent storage of the layout and stock. Earlier this year I took delivery of a kit of parts to build a new home for the layout.   Over the past few months with the help of friends the shed is now finished and yesterday I moved Barrow Road into it's new home appropriately christened 'The Engine Shed'. The intention is to make the layout a continuous run for the main line complete with a fiddle yea

Bristol Barrow Road - 20ft WorkshopTurntable Update

Since my last entry I have made the majority of the track situated at the rear of the roundhouse. This trackwork is quite interesting as it not only links the two 20ft turntables but gives access to the workshop at 90deg to the turntables. Two spurs off turntable 4 run alongside the boiler house and were used for storage of withdrawn engines [Pugs 51218 & 51217 together with Johnson 3F 43444 are known to have been on these tracks]. Turntable 2 gives access to the water softening plant [ wago

Bristol Barrow Road - The 20ft Workshop Turntables

The Workshop at the rear of the roundhouse was accessed through the shed - across the turntable - and via four 20ft turntables one for each of the workshop repair bays. By the 1950/60s - the period I am modelling - only two remained in situ the other two having been removed. Repair bay 2 remained in use for minor repairs whilst bay 4 contained a wheel lathe. Wheels were dropped on the hydraulic wheel drop and rolled to a small turntable at the end of the wheel drop road [ Number 14 ] and then i

Bristol Barrow Road - Roundhouse Ventilation - an update

I have just finished fitting the 22 smoke hoods and chimneys to the roundhouse roof trusses. In order to enable future maintainence I decided I needed a method that allowed easy removal and chose to use two lengths of 0.8mm nickel silver wire to fix and support the piece brass tube used for the chimney section of each unit. These can been seen in the attached photos.   I also needed a suitable height jig to postion each unit at the correct height and orientation in order to mark the position f

Bristol Barrow Road - Roundhouse Ventilation

Roundhouses used a variety of smokehoods for smoke ventilation and Barrow Road was no different. In Midland/LMS days these were made from timber and at number survived late into the BR period. However these were replaced by asbestos/concrete units which lasted until the end of the steam period.   Timber Smokehoods inside Barrow Road   Smokehoods - Roads 11 to 16. Note that roads 12 and 14 retain the timber version.   My friend Morgan kindly produced a CAD drawing for the later version

Bristol Barrow Road - The Workshop Roof Ventilation

The Midland roundhouse roof has slatted ventilation louvres along the full length, on both sides, of each of the three roof pitches and although a number were missing during the 50/60's they still pose challenge to accurately model them.   As a trial I decided to try and model the rectangular roof ventilator situated over the machine shop in the Workshop building. I decided to use 2mm x 1.5mm 'T' section brass in which I cut 8 x 45deg slots using a piercing saw. 16 of these were made, three

Bristol Barrow Road - The Workshop Roof Trusses

Following on from my last entry here are a few pictures of the roof trusses for the Workshop.   These are assembled in a jig to give the correct spacing for the trusses.   The Machine Shop is to the left of the building whilst the four road workshop is to the right       During the 1950's only two of the loco turntables, which gave access to the workshop, remained in use - roads 2 and 4. I have made these doors operational whilst the other two are closed. Road 4 will need to be f

Bristol Barrow Road Roundhouse - Third Roof Pitch

Having got past the summer break and all the house and garden work I have spent the past few weeks working on the third and final roof pitch for the Roundhouse. This required a modification to the assembly jig as this roof pitch is sectioned to permit viewing of the inside of the shed. This morning this pitch was test fitted and a few photos taken.....................             Next task - to make a jig for the Workshop roof trusses.   Edit Monday 9th.   The jig and the f

Bristol Barrow Road - Templot & Trackwork 2

I have now completed most of the trackwork on the existing boards with only the South Exit turnout to finish the second phase of templot. The latest build consists of 8 turnouts, a Double Slip, 3 Way turnout and a catch point. Phase 3 will be the 2 new boards - to be constructed - one at each end of the layout which will form the scenic breaks. One will be Lawrence Hill Junction itself, with the road overbridge and the other Days Road Bridge at the rear of the shed.   Lawrence Hill Junction si

Bristol Barrow Road - Scalefour North Retrospective

For those who missed Scalefour North earlier this year the Scalefour Society have just added a selection of photos of my layout on the Society website.   http://www.scalefour.org/shows/S4North2013/BristolBarrowRoad/   Since the show I have been concentrated on the additional trackwork at the rear of Lawrence Hill Junction signal box and have surveyed Lawrence Hill road bridge that will form the scenic break at that end of the layout. I have drawn up a plan for this additional scenic board wh

Bristol Barrow Road at SN

I have just received a disc the some photos of the layout taken during S4N a couple of weeks ago when it was populated by locos and stock belonging to myself, Morgan Gilbert, Dave Holt, John Darch and Paul Hutfield - thanks chaps, I've never seen so many locos on shed. John's freight on the main line looked particularly impressive as did the Gloucester passenger with Morgan's coaches. The following photos are credited to the Scalefour Society courtesy of David Brandreth.

Bristol Barrow Road - Templot & Trackwork

A few weeks ago I received the second phase of Templot from my good friend Morgan consisting of the south exit including a single slip, Lawrence Hill Junction and some modified trackwork that goes behind the junction signal box to the shed. In the prototype the double track lines, from the Junction, that run behind the junction signal box operated as two single lines, one to St.Philips Station and the other to the Carriage Sidings, St Philips Goods Yard and the Cattle Dock, however for the mode

Bristol Barrow Road - Roundhouse - Second Roof Pitch

I have made good progress since my last posting and the second roof pitch is now finished and test fitted.   In order to fit the roof pitch on the sidings side of the roundhouse the side wall required some modification to position and fit the 22 roof trusses. This meant hand cutting a new set of 22 slots for the new roof, filling the original 13 laser cut slots and the scribing the brickwork. The new slots were carefully cut using a fretsaw, scalpel and drill - an interesting exercise.   I h

Bristol Barrow Road - Test Fit of First Roof Pitch

With the layout now fully erected again following the Christmas and New Year break - the room doubles up as accommodation for guests - I have now had the opportunity to test fit the first of the roof pitches on the roundhouse girders.                 In the meantime I have managed to build another 14 trusses so hopefully the second pitch is not too far away from completion.

Bristol Barrow Road - Breakdown Train - Identification of Stock

I have been looking through my collection of photos taken in and around Bristol Barrow Road shed during the 1950s and 1960s and have noticed two photos of what I believe is the shed breakdown train in the sidings alongside the shed. Is anyone able to assist in the identification of any of the three vehicles, one of which appears to be a modified clerestory of Midland Railway origin whilst I have no idea on the other two.   Ivo Peters 1957 - the three vehicles are in the road behind the Mog

Bristol Barrow Road - Roundhouse Roof Trusses - Progress

It has been some while - June in fact - since I posted anything about the roundhouse. Since then I have had a closer look at the structure of the roof and realised that I had seriously under estimated the number of roof trusses required for the roof. Looking at an aerial photograph of the shed roof I plotted the 13 trusses and realised their positioning made no sense. This made me have another look at my collection of photographs and I have now calculated that the majority of the trusses are at

Bristol Barrow Road - Patriot 45504 'Royal Signals'

For those who follow this blog you will remember that after attending the RMweb members day at Taunton in 2011 I purchased a number of P4 locomotives that were painted in LMS livery.   One of these was Patriot 5535 in full crimson lake livery and after much thought I made the decision to strip this livery in order to transform the engine into Bristol Patriot 45504 'Royal Signals' in lined British Railways lined green.   The loco has spent the last 8 months with Ian Rathbone awaiting its tur

Bristol Barrow Road - Board End Protectors

Scalefour South West is approaching in August and when I was invited to bring Bristol Barrow Road to the show I realised the trolley system I have for transporting the layout was not really suitable for this venue. The trolley is suitable for sports halls but not for Wells Town Hall where the main display hall is upstairs and the lift is not big enough.   With much of the trackwork now in place the ends of the boards needed protection to prevent damage to the track. Similarly some of the board

Bristol Barrow Road - Roundhouse Roof Trusses

The roundhouse kit of parts provided by York Modelmaking contained 13 roof trusses that were cut from 2mm mdf, but having made the decision to replace the two main girders with metal versions I decided to go the whole hog and replace the roof girders. Now I know some will think this to be foolish but I have concluded that the mdf versions are not robust enough to facilitate removal of sections of the roof for display purposes.   the mdf version of girders and trusses   This decision has no

Bristol Barrow Road - Turntable Pit for 60ft Cowans Sheldon turntable

I have been at Railex all weekend helping to operate our S4 group layout Brinkley. One of the highlights of my weekend was collecting the Turntable Pit for the 60ft Cowens Sheldon turntable used in the roundhouse.   Thanks are due to Morgan Gilbert for all his hard work with the design and the CAD modelling and to Phil Hutfield for producing the turntable pit on a CNC machine out of an acrylic polymer - [brand with-held].   I have attached some photgraphs which show the pit in position.

Bristol Barrow Road - Pete Harvey PHDesign Buffers

Before I show the PHD buffers here are a couple of photos of the nearly finished set of buffers in position at the end of the head shunt.       Two sets of buffer stops on Barrow Road are very similar to the design catered for by Pete Harvey's etch, which consists of a set of suitably shaped brass plates and rail jigs. The following series of photos give an idea of the build sequence.               Two pads of double sided pcb have been added to the beam in order to
