Hi Dough,

which glue and which ballast are you using to get realistic looking track beds ?

BR,

Hi Seigfried

There's no special trickery involved here.....just the simple fact that if you feed just the right amount of visual information, then the human brain has this feature that it automatically adds a level of detail to what it recognises.....and things look a lot better than they really are!

Believe it or not, I painted a strip of 3-ply wood with brownish acrylic paint and then simply superglued the track on top when the paint was dry.

The end result then gets mixed up amongst the large number of other "low resolution" finishes.....giving the viewer the impression of there being a high level of detail! You just have to then discourage the use of macro lenses!!!


And on the bridge structure itself, the sections of flexitrack simply slot into shallow matt black painted "T" section slots in the top surface of the girder elements.

Having been so busy involved in other things, I've been neglecting the forum....and haven't said anything about The Bridge being invited to the Spalding MRC show over last weekend.

The show was quite busy...and there were many visitors that hadn't seen T gauge before....but also a lot of visitors who'd seen the layout before...and were enquiring about my next project!!

One outcome from this show is that the layout has got to have some TLC before its next outing. Track joints are getting very worn and loose, etc, and the signals all need replacing...as does the temporary wiring I did when I fitted the DCC boxes. I had a fault develop at one end of the layout that prevented me using the automation...and I had to run trains manually.

Hi Dough

Well your layout has been out alot and T-guage is still new for building layouts up and then packing them back down so I think that it has done very well on the wear and tear. :)

Hope you can still hav the singal lights all repaired as this really wows the audiance with how small it all is. :D

Regards
Graham

With three weeks to go to the next outing, I thought I'd better get the layout out of storage and look at the issues I identified last time out!

Assembled the electrics and checked the track sensors.....all worked after a few tweaks of some of the sensitivity pots. Signals checked and one signal completely missing!!! All other signals in working order.

Placed an order with TGauge.com for replacement flexitrack and track joiners. I'm going to swap out all the loose straight sections for nice & straight new ones. The old track will come in useful on the Saltash layout for behind the scenes areas.

Having had deep thoughts, I've come to a decision that this year, 2019, may be the last season I will be accepting invitations to take The Bridge out to shows.

This year will see the layout at four shows...and the layout will have made it to England, Scotland and Wales...which is not bad. And the total number of shows will be 24...which is pretty good. This retirement (which may even be semi-retirement) is to allow me to concentrate on getting The Bridges at Saltash finished and ready for what might be an equally long run of shows

The Bridge will be stored away in an "almost ready to run" state. I will resist totally the urge to "rob" it of bits so it can be brought back into service some day in the future if needed.

But there's four shows to go......so lets not get sentimental yet!!

With a double weekend of shows coming up in around 4 to 5 weeks, I'm having to step back from Saltash....and get one or two running issues resolved on The Bridge....

I've been having issues getting more than one train running at a time under script control under CBUS. The script works perfect for one train.....but I've designed the script so it can be run two or three times together with each script running one train....and the signalling logic keeping them running in sync. But....for some unknown reason, the DCC throttle control in the second and subsequent script fails to register the power unit.

I'm also limited by the number of DCC trains I have available. I have the two existing DMUs...a 158 two-car set and a 170 three car set. I need to get a couple of extra running sets installed with DCC boards.....and what I get running will depend on how things pan out.

Hi Doug

Good luck with getting your DCC chips in and wiring them.
I have not gone down that route yet as I am very new to DCC concept.

Great that the layout is still running very well as you have done quite a lot of exhibitions with it. :D

Just been browsing on YouTube...and I'm amazed that videos of The Bridge are coming up at positions 3, 7 and 29 when doing a simple "forth bridge" search....even after all this time!! :shock: :shock:

I think I've finally cracked the issue with only being able to run one train at a time under script control. A strange mix of not using the "Extended throttle" type and opening up windows on the controlling PC in the right order!

For a written reminder......start PanelPro, start two or three throttles, assign trains to throttles in order throttles loaded, start train running scripts, set up script settings one at a time.

I've had to modify the scripts to make all variables unique (ie prefixed by "self.") and added in a couple of initial values to ensure the script doesn't lock up!

Next task is to put a couple of power units in a vice so I can squeeze in a DCC decoder in each.....this is going to be fun! :)

They're not the vinyls you sent me....but it is your artwork!!

Your design must have been based on an artist's impression of the livery...and the nose fairing colouring on the real thing is different...its all blue with a yellow rectangle around the window and lights. Also, I couldn't get the vinyl to mould around the fairing properly....the vinyl is too thick for the small curves.

What you see above is your artwork with the nose colour altered, and the whole image brightened up by about 10% to make the fine details stand out better. The result was then printed onto white waterslide transfer paper for inkjet printers, a thin coat of spray matt varnished applied, and with a little help from MicroSet transfer setting solution, they went on a treat! Fiddly.....but an excellent finish!

That looks like it is to commercial / RTR standards. Well Doug, I think you've just raised the bar for the rest of us. :-)

With less than two weeks to the Bridge's final outing for the time being, I now need to clear space in the workshop and start checking out what needs repairing, etc.

I might even have one last go at sorting out the scripting to get multiple trains running......there's got to be a right way of doing it!! I need to cure this once and for all,,,,not only for this layout, but for Saltash as well! And I want to get the nice and shiny Scotrail HST running along with other stock!

Part way through prepping for this coming weekend's show....

A couple of minor scenery repairs at the Dalmeny end sorted so far.....and I might have finally cracked the problem with the scripting not working correctly. More of a start-up sequence for things on the laptop than any errors or missing bits in the code! I have resized the script displays to get windows showing side by side on the laptop screen....which is obviously smaller than my desktop!

Well....now the Models Weekend at Crich is over, The Bridge is now officially in "semi-retirement" and will be put in storage. I'm not accepting any new invitations to take the layout to any shows for the foreseeable future....however I am open to any "special" invitations that may come along that may make me decide to bring the layout out of retirement.

The layout did start showing its age over the weekend. Friday evening saw me having to trace and repair two faults in the track power wiring.....both fatigue breaks of wires at connectors! And during running on both days, I was plagued with bad connections at track joints...despite having fitted brand new connectors!! Perhaps the layout was trying to tell me that it was ready for retirement...

A few stats....

24 shows in three years. 50 show days. Five "Best in Show" awards, one "Best visiting layout" award, and one "Best scenery" award. A few appearances on TV for both the layout and me, Rolling stock covered in excess of an estimated 35,000 scale miles (over 75 real miles)……..

Not bad for my second layout ever! and not bad for a T gauge layout.....holding its own against the established gauges!
