GREEN PARK TRAIN SHED update   Leave a comment

HI Guys well I’ve been a bit remiss and not kept up with Andrew’s further development work. It started with:

Something that has been in my mind for a while is additional loco storage in the fiddle yards. One possibility is adding a siding off the new express siding and running it back to join the outer siding at the far end.

Having gone through stages of development:

Andrews current thoughts:

Sidings all in and before spending what will be some time fitting point motors and wiring back to the control panel I’ve been doing some assessment of siding use. When you think that the original 3 sidings held a 3 coach train + loco. The Radstock empties and Jinty + WR railcar,  and 3 locos I’ve not just doubled the space available but tripled the storage space. So worth the effort.

You can see from todays photos that I’m just short on the longest 2 sidings for a 7 coach train + loco. The loco storage roads are really only suitable for 3 locos each not 4 as planned.

Slightly annoying having measured the space available. I am just a surveyor after all ………

I’ve reassessed the arrangement of the points and there is an option that gives me the extra space available and only having to widen the boards by 2 or 3” so minimal extra work.  

Means I comfortably get 4 locos in each on the loco storage roads and most importantly sidings 1 and 2 will then definitely hold 7 coaches + loco

I’ll sleep on this overnight but pretty much made my mind up that its worth the extra work.

NEW LAYOUT  POSSIBLE ALTERATION

Time to get on with the steam and exhaust connections to the steam chests. Exhaust first as its lowest. But with the engine having a double chimney not a single fixing the smokebox was the first task.

Having done that the blast nozzle position is identified(different from the drawing)

As you can see above running screws were used on the exhaust side but felt they would not be suitable for the high pressure side. Hence this below.

Another own design as I could not see the point in having a bottom connection for the oil which you could not get at. Pretty nerve racking silver soldering it without damaging the threads. But it worked.

Only to find the valve rods just fouled the outside piping so a little fettling required.

One of those projects you do to fend off coronavirus boredom.

The valve rod looks out of alignment as the screws on the valve body are not located.
Yes it was stopped and restarted.

Now to decide on what colour to paint it and fit it to the locomotive.

HI Guys

Been working on the roof glazing. Thought this made an interesting shot.

DCIM\100GOPRO\GOPR7848.JPG

Working on the 6 new Dapol Mk 1’s that arrived Thursday. 3 of the 6 Maroon Mk 1’s ordered and the 3 green SR Mk 1’s. Posted a report on the Guild Forum under RTR if you haven’t seen it already.

Coaches are very good and very fee running. I’ve been converting the Brake ends to single link coupling to make coupling up easier. Between the coaches they have KD type coupling which gives a very good close coupling which extends on curves.

At the moment I’ve worked the 3 maroon coaches in with my Westdale and Gresley coaches to form 2 express sets and the 3 SR Mk 1’s form a local/semi fast set.

7F 53805 (EX S&D 85) arriving with the northbound Cleethorpes express. A SR set and a Maroon set worked this express exchanging ‘ends’ each summer Saturday.

A year of lockdown and enumerable hours of fettling to get the valve motion built and I slowly seem to be getting somewhere.

New piston rings from ptfe.

Various bits of valve motion being machined.

What happens when your mill stem clamping bolt shears its threads.

But surprisingly the part was saved.

Set up in front dead centre the reversing link is held in a vertical position so that when the reverser is moved it imparts no movement to the valve.

Once is checked for the same in rear dead centre the length of the eccentric rod can be identified.

Hi Guys

Been hard at it over the weekend. More work on the front roof.

Attached ‘L’ beams to the base of the ‘X’ trusses ready for the glazing bars to rest on. Painted them all and glued in place after carefully measuring out (more than once!) to make sure that they are correctly spaced over the Bow string girders.

Spent I don’t know how many hours sticking 1.2mm ‘T’ bars to the plastic roof strips. All at 20mm centres and this afternoon glued these glazing strips to the ‘X’ trusses. So this side of the roof complete. Ordered more plastic roof panels and ‘T’ bars to be able to complete the far side and sections of the rear roof .

Finished the in-fill panel and the pitched roof. All parts pinned and glued to just one pillar and glued to the infill panel. Time will tell if it takes the use!

NOW YOU SEE IT                                                                                        NOW YOU DONT …….

Definitely worth the effort as add substance to the overall station and roof and fills that uncomfortable blank space on the left.

Ivatt 4MT 43012 has arrived in Platform 2 with a semi fast from Bournemouth West –  Bristol TM. Built in 1948 at Horwich Works (Better known as Mansell Street works Greenford!) and with double chimney and sent to Bath 29.1.1949.

The first 49 of the class of 162 were built as such but they very quickly showed poor steaming and after much testing on the Rugby Test Plant the drafting was sorted and the remaining 113 of the class were built new with single chimneys with the original 49 having their double chimneys changed to single on subsequent works visits.

43012 did not last long on the S&D finding the high rates of steaming on the long banks just too much in double chimney form and was re allocated to Bristol Barrow Road 22A in 1950. Moving on to Saltley Shed 21A and then off to the Midlands for a while before returning to Saltley shed in 1960 for 2 years and put in more appearances at Bath Green Park on workings from Birmingham.

As I thought the front part of the train shed has gone together much more quickly than the rear as a lot of prep already done and probably less than half the size. Pillars in, Bow string girders in, side bow strings fitted, cross members fitted. Well as far as I can go I’ve run out of the under roof trusses and have ordered some more laser cut trusses.

Platform 2 looking in to the platform ends and, swinging the camera round, looking out passed the Bonded Store at the weekends new construction. I’ve camaflouged the track that cuts across the platforms. The roof is in place but not fitted until I have the extra roof trusses and the slate roof covering.  The bow string ‘X’ trusses are temporarily held in place with some of Hilarys hair clips –  dont tell her! Roof for the far side still a card former as yet to be cut, painted and fitted.

I’ve split the roof over P2 by inserting an acrylic panel to be able to look in and see when uncoupling a double headed express in P2 – hand has to go in through Bay 6. Not ideal but most expresses use P!

Waiting on an order of various ‘T’ bars to be able to go on and do the roof glazing panels. Ordering some more of the roof slate panels.

I had some serious concerns about painting the front screen and how to do it without getting paint all over the plastic panel that it’s all mounted on.

Had a lightbulb moment a couple of day ago and got hold of one of those tester pots of Matt Ivory emulsion. A perfect colour match and if I got any on the plastic panel could easily remove with a bit of plastic scraper. Perfect and painted it up whilst watching the rugby yesterday.

Going to have a bit of a think about the back scene. I used what I had to hand but I think I can do better. The gap in the roof to access and uncouple locos in P1 and P2 is now a lot smaller than first designed and I’m thinking about constructing a lift off fill in section to match.  

I’ve got a couple of pillars to realign but hopefully now within a couple of weeks or so of finishing this rather BIG job.

Been working very hard on fitting the ‘X’ truss beams on top  of the bow string beams. Mounted all 6 large and small ‘X’ truss beams.

The glazing bars are made from ‘T’ section Plastruct. !.6mm for the longitudinals and 1.2mm for the actual glazing bars at 90’. Segments of 10” so just over 2 per roof run. 15mm apart and have a 10mm overhang in each case. One of those jobs that can be done in front of the TV making up the glazing bar segments!

At the moment the glazing bars are only occasionally tacked in place. I now have to glue all 200+ !!!!!!!

Am pleased with the overall results so far

One thing that I’m considering: in my period 1950’s/60’s a proportion of the glazing bars were missing. Removed I suppose due to rust, decay etc . Now do I do similar or ignore this for the overall look?

You can see the new 5th bow string has fitted in very well. I had to stop today as ran out of 1.2mm ‘T’ section Plastruct so ordered 5 more packs. That will finish off this end of the station all being well by/over the weekend and then next week make a start on the front.

DEVELOPMENTS AT BATH GREEN PARK
As construction of the train shed has progressed I have looked again at various aspects of the train shed design.
The TWO issues are: Combe Down tunnel track that cuts across the middle of the train shed AND access to uncouple locos at the platform ends.
The former – nothing to do there it is what it is
The later has developed further. Originally I thought of a lifting flap in the train shed roof but early on discarded this as the structure just will not be strong enough to take constant handling in such a way never mind the odd heavy hand!
So worked on leaving a gap in the roof for that ‘Hand of God’. After all, this whole area beyond the dividing track was going to be ‘off stage’ and so is a big bonus.
Now that construction has moved forward far enough I can see that I may not need to leave as large a gap as I had first thought.
I plan to add one more bow string as you can see in the photo below.
This has an added advantage that the 3 ‘X’ trusses on the far side of the roof can now run right across from front to rear sections and so amalgamate the whole visually.

The view internally of the extra bow string girder
Today I’ve started glueing the ‘X’ trusses in place on to the main bow string girders.

Both roofs are now painted on their undersides – sooty cream. For me its important that the model looks ‘Shabby Chic’. I’m trying to represent Bath Green Park in the 1950’s and 60’s when it was looking rather past its best.
The glazed roof on the left is, on the original, a solid pitched roof but I’ve made it glazed to allow more light through and allows a better view into the platforms as the main roofs do cover a large area of the platforms.
