PNP bar rail chairs survive -20C

We recently received this from a customer. Interesting to note the temperature range that the bar chairs are subjected to, especially in relation to our recent post about their use in Canada. Many thanks for sending this in.

“My son’s garden railway is in Northern Italy close to the foothills of the Alps. It is, at the moment, an end to end run of about 155 yards in length with a passing loop of about 15 yards, but there is ample space to extend this to a continuous loop of about 400 yards. Family matters are ensuring that progress is very slow, but I know that I have taken out enough of your bar stock chairs to get at least 2/3 of the track built! Initially the track was laid on homemade concrete sleepers, but these were very time consuming to cast and have had a small mortality rate over the years. Following a rethink about half the track has been laid on plastic ‘timber’ purchased locally.

The track bed under the sleepers is at least 4″ deep, sometimes in a trench, sometimes on hard core, with about another 1.5″ ballast around the sleepers. In 10 years since the first lengths were laid nothing has moved significantly despite temperature variation from -15C to 35C regularly and -20C to 40C in extremes. Just for your interest the long straight is 70 yards long with the bottom half on a 1 in 50 gradient and the top half at 1 in 40. 

The blue loco featured in one of the photos is my Phoenix Locos Titan 5 “Alpine Courier” which I have taken over there on 3 occasions to give it a change of scenery. Purely for you own amusement in these rather boring times, if you look up ‘Alpine Courier’ on YouTube then find the one labelled Bellaria Alpine and Northern, this was filmed over the full length of my sons railway one lovely afternoon when we had nothing better to do than play with trains and cameras!” 

We really do enjoy reading about your installations and projects and seeing your photos, so please do send them in or post on our Facebook page. And we look forward to being able to sit in the sunshine and play with our trains again.

Just how low can we go?

We recently had a request for a repeat order for a bar rail chair suitable for ½” x 1” hot rolled steel rail. The last order had been placed in 2005 for an installation in Canada where they do not have access to metric bar rail.

But this re-order came with a rather unusual question: At a track-planning meeting yesterday the question of low-temperature tolerance of your chair material in a Canadian winter was raised. Can you tell me what the usable temperature range is for the chairs please? In our location the extreme low temperature would be about -20C on rare occasions. A normal winter low would be in the -5C to -10C range.

We had to put in quite a bit of research on this alongside the suppliers of the polymer. Although the manufacturers did not specify a minimum usable temperature in their data, we had been given a verbal assurance previously that it would withstand the temperature range requested.

Reassuringly for users of our metric sized chairs, these are also made from the same weather resilient polymer.
So, as we speak, 800 of these chairs are en-route to Canada. We will endeavour to find out how they faired in the depths of a Canadian winter.

The imperial chair is shown below alongside PNR-12K metric bar rail chair and below that in situ in Canada.
We are considering putting the imperial measurement chair into full production and adding to our website as a stock item. Do you think that it would be an item that would be of interest? Please do let us know.

Make ’em look rusty they said………………

t’s a bit of a juxtaposition really. Manufacturing a brand-new product and then getting very intense and spending a not inconsiderable sum of money to make them look aged, weather beaten and corroded. But that’s exactly what we did with our PNP railways chairs.

It’s very important to us, and I’m sure you, that everything about your miniature railway looks as authentic as possible. So, we kept at it, varying the colour blend, moulding hundreds of chairs and then lining them up on a big bench to see if we had achieved the look we were after, until eventually we were happy. What I mean is we kept at it until the boss was happy. They really do look like the real thing. (Why does that make me thirsty?)

Rusty Chairs

 

 

 

 

But one thing that, thankfully, isn’t authentic, is the price. A collection of five cast iron railway chairs is on offer on E-bay at £300! You can get one of our chairs for as little as £0.13, which you could look at it as a saving of 99.96%. What a bargain.

So, six words that you, and definitely I, need to remember about chairs:

Wood – Plastic – Screw – Clip – Surrey – Bar

Wood: Because we make plastic chairs that can be mounted on wooden sleepers

Plastic: I think you can guess this one, but just to be thorough: We make plastic chairs that can be used with our own plastic sleepers.

Screw: We make chairs that be fixed to either wooden or plastic sleepers using screws. and are suitable for light and heavy use including club and commercial environments,

These are ideal for garden railways and indeed club use if 5/8″x 5/8″ rail is considered adequate for the weight and traffic to be handled.

Surrey: We make a standard scale or narrow-gauge Surrey rail chair to go with our 5.2ib yard flat bottom steel rail. These have a 3° cant and are for use with our 7¼”plastic sleepers or can be mounted on wooden sleepers.

Bar: Because I’m really getting ready for a drink……………….We can supply chairs to secure 10x20mm or 12x30mm bar rail to either our plastic sleepers or wooden sleepers.

The other thing that my boss told me to mention is that all our chairs are manufactured using a very tough, rot and frost resistant and UV stabilised polymer. In English that means they are made from hard wearing plastic. Oh, and you will also benefit from automatic gauge widening if you mount our plastic chairs on our plastic sleepers.

There is more, isn’t there always? And pictures and diagrams and technical stuff with words like “gauge” and measurements but if you want to immerse yourself in that then why not take a look at pnp-railways.co.uk  and immerse away.

NB When I say “our” plastic chairs and sleepers that is because we really do manufacture them, right here in our factory in a very pretty part of the Cotswolds called Woodchester from whence I pen this article.
