70th Year News & AGM


Gas Tank Test

by David Halfpenny (1802)

My article in NL&J 258, about undeclared Propane in ‘Butane’ canisters, caused some to query the robustness of homebuilt tanks designed for Butane Only. To get a feel for the issue, the Committee tasked me ‘To test a gas tank to an existing design to ascertain the pressures it is able to withstand.

I chose Dick Moger’s elegant 80ml design from the G1MRA ARM1G book. Barrel: 20-gauge copper tube 1.75” diameter by 65mm long. Endplates: 16-gauge un-flanged copper plate. Central Stay: 1/8” diameter unthreaded bronze. Filler Bush: Ronson-fit M4.5mm x 0.5mm with O-ring recess. Feed Bush: 1/4” x 40tpi. Silver-brazed throughout.  The builder had tested to 300psi which had domed the endplates slightly.

Inspector, Fred Roberts, G1MRA Technical Secretary, with myself - Deputy Yorkshire Group Inspector – as witness, checked my gauge against the G1MRA Master. A cheap and simple test rig sufficed to make the test. We filled the tank with water and pressed it by stages to 180psi (Butane Only test), then to 300psi (the builder’s test) and then to 400psi (2018 Code test). Neither increased the doming. At 500psi (Roundhouse test) there was some slight extra doming. Finally, we took the pressure to 600psi (Accucraft test). The shape of the increased doming showed the stay to be effective.

That pressure is roughly three times the maximum pressure of canister gas at domestic hot water temperature. The tank itself remains completely serviceable.

Gauge 1 North News

Gauge 1 North 2017

Gauge 1 North 2017 which was to take place at the Bakewell Agricultural Business Centre, Derbyshire on Saturday 2nd September 2017 has been cancelled.

We are very sorry to have to take this decision, but major clashes with two other shows on the same date has meant that a number of our regular trade stands cannot attend and that puts the viability of the event in jeopardy.

The good news is that the next show has now been set for our traditional summer date and will take place on  Saturday 14th July 2018

Should you wish for any further information about the Yorkshire Group, Gauge 1 North, the Bakewell Show, or attractions around Bakewell that you cannot find on the website please get in touch:

Notes about membership renewal

Membership Renewals

If you already have a bank standing order payment instruction in place you need do nothing more than relax and enjoy another year of gauge one with the Association. Thank you for paying by standing order, it really does help with the admin.

If you are opening a Standing Order using the form that came with your NL&J note that this should be sent to your Bank not to Warners. When you pay by standing order you should ensure that the reference includes your membership number.

If paying by cheque please make it payable to G1MRA Ltd and send to G1MRA Membership, Warners Group Publications, West Street, Bourne, PE10 9PH. 

Payment may also be made by credit or debit card. By telephone to Warners on 01778 392479, or online which also includes Pay Pal at the link at https://subscribeme.to/g1mra  and click on "renew subscription".  On line payments need the Warners subscriber reference number, E............., shown on the NL&J mailing envelope, or phone Warners.


For many years, the dates chosen for our AGM have slipped backwards from the 30th of November in 1996, the year we agreed to become a limited Company, to this year’s date of the 14th of October. No doubt because members preferred to avoid November travel, with poor weather and the loss of daylight in the evenings due to the clocks being put back.However, this has increasingly put pressure on our ability to meet the requirements of the companies act, when 21 days’ notice of an AGM must be given in writing to members.I won’t bore you with the complications of this matter, but will assure you that members of the Committee and Directors have spent many hours working on this problem, and are pleased to say a solution has been found and that includes a change to the deadlines listed below, for the noted issues.

Year 2017. 254 15th May. 255 1st August. 256 1st November.

Year 2018. 257 1st February. 258 15th April. 259 15th July. 260 15th October

Year 2019. 261 15th January. 262 15th April. Etc.: Etc.: 

Obviously, the months of publication are also changing, and two good things to come from this change are, a Pre-Christmas Edition, and a reduction in postage costs. The second is because your calendar will now be sent with the December Edition and not with that for the AGM edition in September, putting both in the same envelope used to put our postage costs over the limit.I am advised that some Advertisers will enjoy the benefits of a Pre-Christmas Edition, so I ask them to note the changes and dates and to contact our advertising manager ASAP.

These changes will be noted in the information panel, found towards the rear of the NL&J.

Outsourcing of the membership function became inevitable due to our longstanding difficulties in finding someone, since the resignation of the previous office holder, to take on the onerous role of Membership Secretary.

No doubt at some point in the future, a member with the ability, time and commitment to perform the role will volunteer; however, it’s simply not credible that G1MRA will always have the benefit of such a resource. In addition, a firm that supplies an outsourcing service to a number of clubs or hobby associations, covering tens or hundreds of thousands of members in total, can offer a more consistent service to members than one single individual.

An informal show of hands at last year’s AGM approved membership outsourcing in principle so around the turn of the year, G1MRA sounded out potential suppliers. The company called Warners won the subsequent ‘beauty contest’; if you’re a member of the 16mm Association, you’ll already know the name as they handle their membership function too. Note: The Warners that we are dealing with have no connection to Warners Leisure.

Unsurprisingly, implementation is taking up quite a lot of committee time. Many months of phone calls, emails, chaser letters and data input have been needed to update last year’s data into a form we can transfer to Warners. Peter Wood, our ex-Secretary Andrew Pullen and Rob Cant have shared that task between them. The contract with Warners, signed on 24 August 2016, specifies the service we and you, our members, will expect in exchange for the monthly fee G1MRA is to pay. Unsurprisingly, G1MRA has needed some assistance from external specialist corporate legal counsel.

For membership matters, your point of contact will be Warners, not G1MRA, from now on. They will offer a dedicated telephone number to our members: 01778 392479, open between 8am - 6pm Monday to Friday and 9am - 5pm on Saturdays and Bank Holidays, excluding Christmas Day, Boxing Day and New Year’s Day. Warners’ dedicated email address is: G1MRA@warnersgroup.co.uk and the mail address is:

G1MRA Membership, Warners Group Publications, West Street, Bourne, PE10 9PH.

A website, which will permit online payments, is live now at: https://subscribeme.to/G1MRA.

Members should quote their membership number to Warners and should inform Warners of address changes by the 18th of the month prior to the NL&J publication month (January, April, July, September) to ensure their NL&J is not sent to their old address.

We are keeping our existing Lloyds Bank account, so if you pay by standing order for example, leave it in place! Other subscription sterling payment methods available now are: cheque, money order, postal order, bankers draft, (all made out to G1MRA please). With reluctance we will continue to accept cash payments to the Membership Desk (if there is one) at exhibitions, while we expect some or all of the following methods (without limitation) to be accepted at some point in the future: credit card, BACS (online) transfer and PayPal. G1MRA reserves the right to levy an additional charge for expensive transfer methods, like Paypal.

Many of our overseas members make payments through a coordinator, (see the Join US page on this website which has just been updated) and we expect all these local arrangements to remain in place for at least the first year of the contract. More broadly, if there are teething problems, please be patient, as we are confident that this process will be the right one in the medium term.

Back issues of the NL&J will also be handled by Warners. We expect Warners to have the back issue stocks following the AGM.

Simon Hill, G1MRA Secretary

Swiss storage bank

ZUG Safe
Recently another great and unique project has been accomplished and inaugurated by “some Swiss watch makers”: the train storage and lift at the EiWi outdoor layout at Witterswil near Basel – Switzerland!
On this beautiful and instructive video (https://youtu.be/l65z3AQlOQ8 ) by our member Peter Krattiger you see how it works: this is a 4 storey storage shelf, built from scratch by Christian Schmutz and Werner Metzger - G1MRA members and members of the EiWi group (Eisenbahn Witterswil) - works perfectly by an electronic control system. It is housed inside our new barn, next to the outdoor layout.
It hosts 16 trains, each in maximum 9 meters long.
It will be used for the first time in public at the EiWi-Bahndammfest of 2/3 July.
Any questions: to Christian, to Peter or to me, Charles Simon.
Enjoy the video. If your mouths are watering now, come and see it here in Switzerland!

Dobson Bridge has new custodian

Dobson Bridge
We are pleased to announce that David Blamire is taking over from Terry Geeson as custodian of Dobson Bridge, which is of course the GIMRA showcase layout.  We would thank Terry and his team for all their hard work over the last few years in improving the running qualities of the track and making it a really remarkable spectacle for spectators.
David will be looking at further improvements, with the fitting of pattern makers dowels and clips to do away with the chore of having to scramble underneath and use bolts and electric drills to set the track up.
David can be contacted on his email address which is:  david.blamire@mypostoffice.co.uk

Great Moments in Gauge One Video!

Many Gauge 1 videos show unedited footage of an event.  There's Uncle Henry watching his favourite engine pass the water bottles,  ooh and isn't that his pal Fred's hand in the way of the camera.....

However, what the unconnected G1MRA member wishes to see, (warning - opinion not fact!) is footage of locomotives pulling suitable trains at scale speeds with Uncle Henry, the water bottles and Fred's hands edited out. If this is elevated into a cinematic experience  via diverse viewing angles including tracking shots and a distraction-free soundtrack then a quick and easy Gauge 1 fix on a winter's night is obtained!

In our Gauge 1 video gallery  open link as new window here you will see (as at 10/10/2015) a live steam Britannia tackling a 2% gradient with a long train in a Danish garden (Krogen, 4:00) while in Kent a 1% gradient is taken at a controlled canter (5MT, 1.00). Masterful "dolly shot" execution is shown in Buckfastleigh (05:30); Evening Star has never looked so good!

Sometimes the moving pictures tell a story to the extent they appear choreographed. See how the radio controlled start of the Class 4 tank fills the sky with steam while behind elegant teak coaches follow dutifully. By contrast, watch the massive Allegheny's rear engine's wheel spin, then the front engine's; something that is easily done on wet rails by model and full-size alike.

The joke in the Steam Turbine video expresses the thought we all have on seeing M. Jeggli's high revving wonderdrive, while in the simple - but still proudly scratchbuilt - Project video, suspiciously tuneful birdsong forms a backdrop to the opening scene of the static locomotive.

For a change, have a look around the several all-electric indoor mega-tracks as well as the videos of live diesels. And before you go, don't forget to look in at "Pretty Track in E Sussex": count the sleepers, count the chairs and count the ballast stones and then think how long it took to build....

Please note that for technical reasons the only videos that can be shown are those listed on "YouTube".
