Some film of the 7 1/4" rack railway opening up after the winter. We were hoping for some snow to try out a snow plough but nothing arrived in Naples this year. At the end most of the fleet was dragged out for a clean, all of these are the work of one man who manages to build around two locos per year.

One of the most beautiful settings for a line I've ever seen.
Fascinating valve gear – what's going on there?
I hope at least one of them is called Vesuvius? Or is that a bit taboo round those parts? :-)

There certainly is a loco called Vesuvio (Vesuvius), www.ferroviaturistica.it/Le_Locomotive.htmlNothing taboo about the mountain, it brings in tourists by the thousands. The setting is in a park surrounding the castle at Nocera to the South of Naples. From there you look out over the slopes of Vesuvius. It's quite a compact set up but has a bit of everything. The loco in the film has two sets of two cylinders, one set drives the loco during normal working, the other is connected to the rack gear and is used when ascending. Both driven by its own set of valve gear but from a common reversing lever so you can't drive one set of cylinders against the other. |

Looks a very interesting railway with some interesting locos, but those safety valves look a bit small to me for a boiler that size, regards Ian

Ian , the relationship between the boiler heating surface and safety valve is a bit confusing . for the same heating surface , the higher operating pressure the smaller safety valves , it all depends on what is the operating pressure on those boilers . Hope this helps .

Shawky, dont take this the wrong way, I have been building locos from gauge one to large 7 1/4 narrow gauge for 50 odd years so I do know a bit about boilers and safety valves. I still think they look too small, regards Ian

Ian , I have thick skin , I don't take offence , I don't know who builds what , I just try to help if I feel I can .The reason I made the remark is this , I am a boiler inspector and one gentleman imported an engine from Canada or US , this engine was tested for 120 psi but when I carried out the test for 100 psi ( that is our maximum allowed limit ) , the safety valves were not capable to keep the pressure at 100 psi + 10% at full blast , this caused a lot of trouble the guy left the club and went to another club in anger because I wouldn't issue him a certificate unless he enlarged the valves which meant a reasonable major job , the other club tested the engine and demanded the same , he had to do the job and he is back in our club and reasonably friendly , he now understand if it is good for 120 psi it does not mean it is good for 100 psi .The valves look small as you say but I think sometimes image may give the wrong impression .

Probably the last steam up of the season, a new baby is in the process of being born and although had it's first run there are a couple of points to sort out, so pictures early next year www.youtube.com/watch?v=gkqR1KJx8w0 |
