Hi Doug,

Just bought the issue because I needed to see the article. Looks great. Especially the title picture! How was that made?

Congratulations from Vienna

None of the photos were anything to do with me! And I believe a dose of Photoshop was involved! ;) ;) :roll:

I've just accepted an invitation to take The Bridge to the Chiltern Model Railway Exhibition 2018, being held in Stevenage on 13th and 14th January. This show has previously been held in St Albans, but is moving to a larger venue in Stevenage where they can accommodate more layouts....

Well...in one day I've received and accepted one invitation to show The Bridge.....and withdrawn my acceptance of an invitation to take The Bridge to another show!! :shock: :shock:

I had received an enquiry to exhibit at a show in the north west in the winter of 2018, but I have decided not to pursue it due to a couple of reasons......very awkward access to the site and unacceptable selection criteria the organisers have for layouts they invite! :(

Now the good news, this afternoon I was invited to the Festival of British Railway Modelling Show at Doncaster in February next year. This is apparently the first T gauge layout they have invited to the show.....and follows the featuring of The Bridge in BRM magazine. :D :D

Just resting after a good weekend in Worthing. The show was fairly busy and there were many visitors who hadn't seen the layout before...and even a few who had visited the show mainly to see the layout. Just shows BRM readers do read through the details in articles! ;)

All stock ran well...although the Class 170 did stutter at one spot every time through on Saturday. I'd touched up the paintwork on the under-belly of the units as they were looking worn.....and didn't realise that one layer of paint would make the unit stop!. I scraped the paint off the corners....and the unit then ran perfectly! 8-)

I have some repair work to do before the next outing....to Falkirk.....two new signals needed. One had previously been knocked and the head came loose. It was still working...so I did nothing...and when cleaning the track Sunday morning I nudged it once to many times and one of the wires broke, so it lost one aspect. And I must have caught another of the signals with the track insert when dismantling the layout....Its head got knocked off completely! I think I have enough spare smt LEDS!

Signal repairs in progress as I start preparations for the Falkirk show.

And I've just had confirmation of an invitation to another show....the Sheffield Model Railway Enthusiasts 2018 Exhibition on 24th and 25th March 2018.

All repairs now completed and signals all now fully functional.

Tomorrow I can now concentrate on getting the track and rolling stock cleaned and prepped for the show...50 ft or more track to clean and 24 axles/wheelsets to strip out, check, clean and replace. Should be a fun day!!

I'm starting to see signs that my rolling stock is starting to get to the point of needing a major overhaul!!

I think I may need to fit new driving bogies....as I've had to replace three individual wheels .. either a magnetic tyre has come loose and spins, or where the magnetic wheel is starting to break up or wear! I've also had to tweak a few of the metal pieces in the bogies so they grip the wheelset a little tighter.

I'm not that surprised I've found these issues.....these DMUs have travelled a few miles (1:1 scale miles) in the last year 12 shows, 22 days, and at say 5 hours a day running, a total of 110 hours running!! Does that mean my DMUs have each travelled over 100 miles?? :shock: :shock: :shock: :shock:

And its very strange that the most common question I've been asked by show visitors about reliability is "How long do the motors last?".....with my reply being "No idea.....I've never had to replace one!". And this must raise a question re power units/locos in the larger scales.....Do they have fragile motors?

I've been wondering about long-term reliability as well. Your maths seems a little out - I figure 1-2 (real) miles per day given near-continuous running. That is still impressive for any model, and I know OO modellers who are having similar issues. My main concern was actually the bearings on Ozrail's older 4-wheel wagons, but they have held up well - for Sarum, call it 4 shows or about 12 miles.

Congrats again Doug. I'm sure the new Bridge layout will be as equally rewarded.

Now I've recovered a little from the long weekend, I need to document a few things....

The automation system suffered its first major breakdown that couldn't be sorted out. Two of the LDR sensors failed to trigger their respective inputs into the PCB. One on the North side failed to pass its function test...and on investigation, I wasn't able to trace what the fault could be in the time I had. Whilst I was doing one of the many function tests, I noticed one of the LDR sensors on the South side also stopped working. I ran out of time and had to get the layout runnable with two trains chasing each other...which I managed just in time for when the show opened. I then had to spend the two days.....helped by Jim Rusk, who came over from Glasgow both days to help...stopping the faster train at one end of the layout for a while to create a bigger gap, then setting on its way again.

Both DMUs ran very well most of the time. The 3-car Class 170 did go through a spell where it was stuttering....but an application of track cleaning just in front of it a couple of times allowed sufficient alcohol to be picked up and clean the wheels. The 2-car Class 158 ran well most of the time..but one shell started lifting & catching on the bridge girder work. Blu-tack resolved it!

When I was trying to track down the sensor fault, I killed another signal head....which will need replacing.

No more notes....so I can comment on the show....

The show was well attended....and as expected, there were a fair number of locals who had good knowledge of the bridge and the surrounding area. Three visitors pointed out their houses...one who did the so in Glasgow...and two others. And a young lad pointed out the school he had attended up until this year. All were impressed with the accuracy and level of detail......which was reflected in the voting for the "best in Show" award....which I was told the layout was a clear winner. After the show, I was talking to one of the other layout operators ( who I know from the Tramway Museum) who had picked up two awards himself....and he was told that The Bridge was a close runner up for one of the awards he won.

A very good show...and a nice weekend away. I just need to get the issues sorted for the next show in January.....

Just about ready for travelling down to Stevenage. Track all cleaned, Power unit axle sets cleaned...including removal of a three inch long thread that was wrapped round and round a geared axle!

I do have one possible issue with the automation. What I originally thought was a wiring fault on the sensors turned out not to be a wiring fault as all connections were sound. After a quick email exchange with Martin, we concluded that one of the programmable ICs must have gone faulty. Fortunately, Martin had a spare chip he was able to program up at very short notice.....and I'm currently awaiting the clatter of my letter box flap telling me the PIC has arrived from Australia!! Martin posted it Express Delivery ( 2-3 working day) last Friday....so it has to arrive tomorrow!

If it doesn't arrive and resolve the issue....then I'll be disappointed, but I'll still be able to run a couple of trains on the layout....but will have to constantly monitor their progress! If it works, then with the DMU power supply mods, I should have almost trouble-free running for two days....and can concentrate on persuading visitors to give T a try!

For future shows, I might even retro-fit DCC. That is if I get any decoder chips! I'll need to either modify the output module I've already built...or create a new module. With a bit of wiring modification and a bit of electrical plumbing, I could get The Bridge working with DCC!! Now that would be awesome!

I'm in mid-preparation for the show at Doncaster which is now just over a week away....

I've made progress on the issue with the automation I've been having. A New programmable chip eventually arrived from Australia....and having plugged it in...exactly the same!!! After a bit of further prodding around with a meter, I finally established that two of the LEDs on the control panel had stopped working. It seems the sensors were working perfectly......it was the LEDs simply not lighting when they should!!!! :twisted: :twisted: :twisted: :twisted:

New LEDs fitted....and semsors now test okay....but I can't check the functioning of the system without assembling the layout. SO.....fingers crossed for when I get to Doncaster.

I've also bought both DMUs a new set of boots! I fitted the new bogies this afternoon.....and boy do they run smooth and quiet!! :shock: You don't realise how noisy they get when things start wearing out!

Just need to clean the track and give all of the track connectors a good look over...and replace any that might start to cause assembly or running problems.

I'm looking forward to this show......as I'll have some company! Alan and Lorraine will be bringing down the TGauge.com stand...and the kind organisers have put us side by side! So now when I get the "I've never seen T gauge on sale anywhere" line form visitors, I can say "Look next door.....and buy some!!", put them in an arm lock.....and frog march them over to Alan! 8-)

Re: The Bridge

With all the investigation work I've been doing over the last few weeks and months on the subject of DCC and automated control of layouts using such things as computers, tablets and mobile phones.....and the arrival in the market place...at last...of the CT decoder DCX65, I've been thinking quite seriously of changing the tack of my layout development......and I have finally come to a decision.

Prior to incorporating DCC and CBUS into The Bridges at Saltash, I have decided that I'm going to upgrade The Bridge to DCC/CBUS operation. This will accelerate the process of me getting a DCC in T exhibition layout onto the circuit.....which, hopefully, may add to the "Stir" The Bridge has created in the model railway world in the UK.

The process of upgrading will mean I can use some of the DCC/CBUS hardware I have already built for the new layout.....and all of the sensors and LDR detectors I have already installed on the layout. I may need to replace some of the external wiring....but this will not mean any major hacking of the existing layout boards, etc.

As I already have a thread in the General forum section on the subject of DCC ( http://www.talkingtgauge.net/viewtopic.php?f=10&t=525 ), I'll post updates on that thread with occasional links from here as I reach key steps......
