    It was part of a government sponsored post war program. Certainly the GW, LMS and Southern all started to convert selected types of locos before the availability of oil became a problem. Bath Green Park shed had oil facilities installed and at...

  2. torgormaig replied to the thread Oil Firing.

    I think one of the two V4s had a thermic syphon and a steel firebox, the other had a normal copper box. Their early demise was attributed to there being no spare boilers for them when their existing ones became life expired. But as @LMS2968 says...

    With regard to the Pullmans going to Whitby, the K1 took them there in 10/10/1999 as seen here, but I forget what the occasion was. [ATTACH] Peter

    I had a memorable run to Battersby one glorious spring evening firing to Fletch (the late John Fletcher) on Tornado. We only went from Grosmont, not Whitby, and as you say it was a short lived experiement but what a lovely evening turn it was - a...

    Considering that Ahorns died a century ago his comments are hardly relevant to subsequent locomotive development. Steel fireboxes were widely used in the British locomotive construction industry between the wars, just not by the Big Four...

  7. torgormaig liked Jamessquared's post in the thread Oil Firing.

    Not quite, he specifically mentions light oils: The oil used was gas oil or equivalent of low viscosity at normal range of atmospheric temperatures. Although costing more than crudes of high viscosity it was more reliable and obviated the need...

    A couple of points about this oil firing lark, if I may be permitted as someone who knows very little about it. The issue that Tom raises about the need for a steam supply surely refers to the heavy Bunker C type oil used in Holcroft's day...

    You beat me to it!:) I saw this just after I posted the above and was about to copy it myself. Peter

  11. torgormaig replied to the thread P2 Locomotive Company and related matters.

    Thats a bit of a sweeping statement. Surely it depends on the type of oil (liquid fuel) being used. Thick Bunker C fuel is very different to diesel oil which is different again to recycled chip fat. I'm sure that they smell differently too but...

    No. See attached. This paper on the site is the copy in Search Engine. Unfortunately Search Engine's copy is missing most of the drawings (the IMechE told me when I enquired that they have no record of this paper). On the comparative cost of...

    I dont think it does either. There is an interesting website about the current restoration of Alaskan Railways N0. 557, an oil burning S160. It included a video of the laying of fire bricks in the firebox which is clearly without a combustion...

  15. torgormaig liked 21B's post in the thread North Yorkshire Moors Railway General Discussion.

    I suspect that the reason that copper fireboxes may not last as long when oil fired is related to the fact that oil burns hotter than coal and copper melts at a lower temperature than steel. That suggests that you would expect the surface of a...
