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.
