The Yorkshire Group of 16mm N.G. Modellers Ltd

Yorkshire Group  Running Regulations for Public Shows

Gas is supplied for public running on Mount Dowd and Dixon Green. 

Please do not use your own gas canisters at Public Exhibitions.


Running layouts at public exhibitions

Running trains on Mount Dowd, Dixon Green and Saed-y-Parc is essentially public entertainment, showing the magic of 16mm garden railways and the fun we have in running them. Safety is paramount and every runner has to take responsibility for their actions and the safety of themselves, fellow runners, and, importantly, members of the watching public. This is why we have the Regulations and Guidance for the operation of the layouts at public exhibitions.

To run on Mount Dowd or Dixon Green/Saed-y-Parc you need to be a current 16mm Association member in order to be insured.  Junior members need to be supervised by adult members at all times.

We always ask that members let us know in advance that they are coming to steam.  Details are given on the Yorkshire 16mm website.

If you are new to running on the layouts let Andy Cooper [for Mount Dowd] or Phil Thompson [for Dixon Green] know so that they can arrange an introduction to the procedures outlined below on the day.

It is important to understand and follow the Regulations and Guidance for each layout noting the different particular practices for preparation, running and disposal of trains.

Remember that at a public event you are not primarily running trains for your own benefit. You are giving a show to a paying audience. They have a right to expect the show to be as good and as safe as possible. 

Dixon Green and Saed-y-Parc


Mount Dowd

No meths fired locos are allowed.


Running on Mount Dowd

Mount Dowd has 3 running tracks, an access track and sidings to make up and dispose of trains.  Two trains can be run on each of the running lines in any 30 minute slot.

           [BLUE] the middle and inner tracks run anti-clockwise.

Running Roster

Enter your full name in the roster slot. Make sure you meet and know the name of the other person who is running with you in that booked slot.


Please make sure that you turn up to run on time. You should know how long you loco takes to prepare.  Run for the full 30 minutes so that there are not big gaps in the schedule. Mount Dowd has no gradients so gas can be turned down very low ensuring a longer running time.

If you become unable to make your booked slot, please cross out your name as early as possible to enable another member to run in that vacated slot.


Radio frequency and control

It is assumed that everyone is now running on 2.4g.


Anyone not on 2.4 e.g. 40/27mhz should check that no-one else is running on their frequency. It is wise to do a trial check before you steam up to check that there is no interference on your channel from other exhibitors’ layouts.


General safe running

If you are in charge of a steam loco, it is your responsibility to ensure that it’s both safe and reliable and you are familiar with its operation especially lighting up procedures.  Always run your trains with the utmost consideration for others. Drive at realistic slow speed and in a reasonable manner.


Never put a loco or stock on a main running line unless you intend to run it properly.

You should not bring a loco to test on Mount Dowd when the layout is being operated at a public exhibition.

If your loco gets into major difficulties, remove the entire train and let other drivers continue the show.


At the end of your booked time, check with the other runners about leaving the running lines. If the next runner isn’t ready you may be asked to fill in for a short time.


When you have left the track remove your engine and stock immediately from the tracks so that it does not obstruct those assembling trains.

DO NOT leave your engines or stock on the innermost YELLOW circuit

Be sensible about where you stow things inside the layout. Loco boxes, stock boxes and loose tools can easily get in other people’s way if they are left lying around.


Fuelling and Re-fuelling

Before you begin to prepare your loco make sure you know where the layout’s extinguisher/fire blankets are kept and how to use them.


Gas/fuel your loco on the table in the centre of the layout.

Lighting-up a steam loco is potentially a dangerous activity. Remember that because of the noise at a show it is hard to hear if the gas burner is lit. Butane is heavier than air and sinks. Make sure that you are especially vigilant when other members are fuelling with gas or lighting their loco. 

Please be especially careful if you are running a loco with an open-flame boiler or pot boiler [e.g. Millie or Mamod] or a coal-fired loco with an exposed firebox that is more likely to ignite airborne gas. Let other runners know so that they can take this into account while topping up or lighting.

Light the gas burner on the track and away from the gassing-up table.

The INSIDE steaming up lines are ideal for this. Do not attempt to light up while an engine is passing by.

You can top up the gas on your loco on the steaming up lines once steam has been raised.

You can top up gas on the outside line in the loop/headshunts.

Do not top up the gas when other locos are passing.


At public exhibitions only coal supplied by the Yorkshire Group may be used.  This is to ensure that no nuisance is caused to the public or traders by excessive smoke and smell.  Coal will be made available for members to use at Exhibitions. Contact Andy Cooper in advance.

Disposal – always dispose of the ash/fire safely.  This will include bringing something e.g. a piece of tinfoil to place under the engine so that the plastic track is not damaged.

Finally, if you are asked to stop steaming because you are not following these regulations in a safe manner, please do so straight away.
