Bristol Barrow Road - Lawrence Hill Junction Signal Box - Update 2

After a call out this morning to sort out my son's car, I managed to do some more on the box this afternoon.   Both ends are now assembled and have been test fitted against the front elevation. The corners interlock very well with the front elevation and are a stepped design to form an overlap with the four laminated layers of each piece.     Next the rear elevation......

Bristol Barrow Road - Lawrence Hill Junction and some videos

Chris Yates has finished building the 'temporary panel' for Lawrence Hill Junction signal box, another job done for which I am very grateful. I say temporary because it only controls the turnouts at present as I have yet to build the signals.   Chris has built in interlocking on the junction using relays with LEDs confirming turnout settings and the junction with entrance and exit to the shed yard is now fully operational.   Lawrence Hill Junction Panel   Lawrence Hill double junction

Bristol Barrow Road - Photos of some locos in the yard

I am still waiting for the two Masokits etches so I've made a start on an EM GWR Metro tank kit I promised to build for a client a while ago....... feeling a bit guilty about the delay.   In the meantime here are a few photos, as promised, of some of my locos taken around the shed yard.     All the locos on view, apart from 75004, are Bachmann and Hornby origin which have been rewheeled to P4. I have another 40 odd RTR and kits in the stock cupboard

Bristol Barrow Road - Days Road Bridge

Having added the single slip and extended the sidings onto the Days Road board I decide to do some work on the bridge itself. First task was to modify the parapet by removing the 'indents' and straightening the brickwork.     The bridge structure was fixed onto pieces of 6mm ply to form a base to set into the foam on the baseboard top.     The structure was given a coat of Halfords red oxide primer before the brickwork was detailed and weathered prior to a final blend coat of Humbrol

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 - Wiring the layout

Since July, modelling time has been allocated to wiring the layout. The scenic section of the layout consists of boards numbered 1 to 9 and these are the ones I am focused on at present. This part of the layout is divided into a number of power zones - 1 and 2 the UP and DOWN main lines. Zone 5 the sidings alongside the shed; Zone 6 & 7 divide the main yard and Zone 8 the roundhouse. I have added two power buses for the cobalt point motors in the yard which are Zones 3 & 4. Just to give

Barrow Road Roundhouse Update 1

I have added the rest of the templot track plans and added a few locos for atmosphere - most of them are still in RTR state and will need chassis conversion to P4. The templot is in need of some tweaking as it was done with a 55ft turntable inside the roundhouse before I discovered that a 60ft Cowans Sheldon unit was installed in 1927.         The Jinty on road 8 is a P4 converted Bachmann as is the WD on the exit road. All the rest will need converting.

Bristol Barrow Road - Lawrence Hill Junction

I completed the trackwork for the junction at Lawrence Hill a couple of months ago and now that I have the legs for the curved board I decided itwas time to lay the track. The junction is constructed off the layout using a templot track plan and has been constructed from ply sleepers using a combination of exactoscale functional chairs and rivets. I like using the latter on pointwork as it enables adjustment to the track before adding the cosmetic chairs.   Some re-alignment of the track on th

Bristol Barrow Road - Board 21 tracklaying

Board 21 now has the majority of the track laid - just a couple of 60ft lengths to go. All the track is C&L ply sleepers with functional Exactoscale 4 bolt BR/LMS chairs. I've just received an order for a pack of 500 to complete this board. You will see in the photos lengths of black card which I use under the ply sleepers.The card is 0.2mm thick and 6mm wide and has become my standard practice for track laying following a recommendation by Graham Turner - if you need to adjust any length of

Bristol Barrow Road - Storage Sidings Track

Both C12 crossovers are now built, one for each end. Starting at the Lawrence Hill Junction end of the layout I have now extended the hand built track onto the first storage yard board to join up with the C12 crossover at that end. The first B7L turnout from the Up Main to the storage sidings is also built and is test positioned in the following photos. I have built the end curves using ply and rivet construction to make sure the gauge widening is correct. All the straight track in the storage s

Bristol Barrow Road - More Progress

Over the past couple of months I have had to make some modifications to the Dunster House shed building in order to make room to fit the fiddle yard boards down the back wall. This has entailed making cut outs in the two short walls that protrude into the building. After much thought and deliberation I made a decision to add a 6" x 3" wood beam across the two inner roof 'trusses' in order to add strength to the roof. These two beams were supported using 'permanent' acrow props which have now bee

Bristol Barrow Road - Roundhouse Roof

It has been a while since I did any work on the roundhouse roof so I recently added the smoke hood support wires, 4 to each hood, to the 22 that are inside the shed. The roof is entirely scratchbuilt from brass section and nickel silver wire. The smoke hoods are of two types - 3 older wooden types which are ex Midland/LMS in origin which I scratchbuilt from plasticard and brass angle, and 19 'asbestos/concrete' units which are cast in resin by my Friend Morgan from a 3D printed master.

Bristol Barrow Road - Fiddle Yard and some Comet Coaches

Over the past couple of weeks I have added a 2mm layer of adhesive foam to the remaining boards including the seven in the fiddle yard. My choice of a roll of 10m x 1mm 'Envoy Multi Adhesive Underlay' via Ebay has proved relatively easy to lay and economic at just shy of £18 for the roll. The adhesive layer on one side needs careful handling when peeling back the clear plastic covering sheet but once in place it grabs well and sticks. You will not remove it easily. Made of recycled rubber tyres

Bristol Barrow Road - Signal Box - Concrete Base and Roof Slates

Following my recent posting I received two constructive comments from RMwebbers.   I forgot the box stands on a concrete plinth and that there should be steel RSJ's to support the 2 central pillars above the lead out slot. This has now been rectified by adding a layer of 60thou plasticard around the base with the top edge champered. I have just made the pair of transverse 'I' beams to go under central pillars - not fixed yet so not in the attached photos. Thanks for your comments Keith.   An

Bristol Barrow Road - Further Wiring Progress

Further progress on the wiring with Boards 14 and 15 now partially complete. The immediate object is to wire the complete circuit of the double track main line. Boards 14 and 15 are storage yard boards on which the bus bars are now fixed as are the inter board 'jumper' cables. The UTP cab bus units are also now wired.   Board 14   Board 14   Board 14   Board 15   I've just started on Board 16, with just 17 to 20 to go.

Bristol Barrow Road - Storage Sidings and other updates

It's been a while since I updated my blog but we haven't been idle. Chris has made two Power Boxes one for the scenic side and a Booster box for the Storage sidings. Each contain a Maplins X21M Power unit, PSX circuit breakers, a DCC Concepts 12v Power supply PSU2 and NCE Units - a 5amp command unit in the main box and a Booster in the other. They do look rather smart.   Main Power Box   Booster Box   Engine Shed Sidings now has a panel for the turnouts which controls the Fishponds banke

Bristol Barrow Road - Storage Sidings Track Plan

Since my last entry I have had a rethink on the curved scissors crossover. It is critical to the running of the layout and being on a curve I have decided to simplify the entrance/exit of the Up and Down storage sidings by using a single crossover at each end. These will be C12 1600mm radius one will permit trains to access the down main from the UP sidings whilst the other from the DOWN sidings to the UP main.   My decision followed additional work on the working timetable and following the m

Bristol Barrow Road - D13 on test run with rake of Comet Coaches

I have a rake of Comet coaches which I converted from 00 using Bill Bedford sprung bogies and Gibson P4 wheels. These coaches are a fixed rake and have now had Alex Jackson couplings added to each end to enable a test run of the complete set. As they are heavy I decided to use one of my converted Bachmann Peaks, D13, to pull the test train.     For those interested the rake is made up as follows;-   Corridor Brake Composite D1720A Restaurant Composite D1811 Open First - Porthole D2160 C

Bristol Barrow Road - Wiring the Gap

The lift out board - number 19 - has now been fully wired. Power to board 19 is fed via four brass strips on the board which, when the board is in position, make contact with 4 brass sprung plungers obtained from old light bulb connectors. To enable power to still feed Board 20 when 19 is lifted out power cables have been run down the support legs, across the floor and up the support leg of board 20. To avoid the potential disaster of engines and stock being accidentally driven into the abyss a

Bristol Barrow Road - Lawrence Hill Junction Box - The Walkways

Before getting on to the construction of the walkways here are a few photos of the 'stench pipe' fabricated from 1.5mm brass tube bent to a suitable shape with the connection to the loo added for good measure!!   After much thought I decided to make the walkways from nickel silver strip and wire in order to give it a degree of strength and to minimise any accidental damage. Looking at the set of drawings of the 20ft box in Midland Record No 2 there is a good drawing of the handrail cla

I hope you have all had a good Christmas.   I thought I'd share a few photos of the trackwork added during a quiet hour on Christmas Eve.   Well nearly complete. All the track on Board 21 is now in position with just the sleeper staining - Jacobean Dark Oak - and the droppers - Palatine Models - left to do. The track has now crossed onto Board 20 the track ends being soldered to 12BA brass screws which are screwed through the ply rivets. I use a pair of ply sleepers on each side of the trac

Bristol Barrow Road - Wiring Progress 3

I've had a train - Bachmann Peak D41 on Rumney Chassis plus four Bachmann MK1s performing a test run through the storage sidings. The test traversed Board 9 to Board 18 and involved a number of successful forward and reverse moves - I really must register on Youtube and take some videos.   Wiring has progressed further since my last entry with the production of 16 wiring looms for the analogue Cobalt point motors. These are positioned along the double track main line and will be operated from

Bristol Barrow Road - Bridging the Gap

This update covers work carried out since my last entry. The lift out board has been tweaked to ensure it slots into the layout by the shed door. I have replaced the over catches with a more robust set to ensure the board locks firmly into position.     Black card strips have been laid in preparation for the final lengths of track to complete the UP and DOWN main lines.     The second pair of ' King turnouts' for access to the Up and Down Storage sidings and the Second Crossover are
