In general it seems undesirable to use any kind of oil as fuel that could be used as food. Used cooking oil is another matter. Even if you are going to use fresh rapeseed oil, why cold pressed?

No, British engineers weren't stupid but at the end of the 19th century, not surprisingly, they lacked sufficient knowledge of thermodynamics. Even Gresley made the mistake of placing the steam inlet in the P2 cylinder block too close to the...

Crikey! All I said was that it seemed to be a long way from Strawberry Hill to Alton! ;) Tom

Obviously UP* considered their Challenger and Big Boy articulated locos were more than good enough to warrant not going down the compound route. *Other railroads are available.

Yes, like all pretty much all engineering its about tradeoffs. We enthusiasts are very prone to talk about success and failure, but most likely in most situations its more nuanced than that. The French compounds on the GWR, for instance, weren't...

It is nonsense to say without qualification that compounding is good or compounding is bad. The choice between simple and compound expansion is like many choices in engineering, with each having pros and cons. Two factors in France, the high cost...

Well, the Midland compounds seemed to do OK, but yes, the UK loading gauge was/is pretty restrictive. I do wonder how Fowler's proposed compound Pacific would have turned out - hopefully with decent axleboxes, but that's another discussion... Mark

I think that you will find that the match between Churchward's locos and the French Atlantics was fairly equal but only because the former had advanced large, long-travel valves whereas the latter had narrow steam passages and slide valves for...

"Asthmatic figurehead" is cruel but also perfectly accurate. In defence of WC, I dont think they've ever succumbed to using 3 diesels to assist one steam loco on a charter like Saphos LSL did yesterday ....

Isnt it strange that the 10 year olds seem to respond to the posts though.

I have every sympathy with @Big Al’s views, I wouldn’t want to be shoved around in a coffin by a diesel with an asthmatic figurehead up front. However, my solution is simple - I save my money and no longer book any tour that involves WCRC.

There is an old saying when thing go right you tell a couple of people, when they go wrong you tell everyone. In the case of the Tynesider things went wrong and it’s created a lot of comment but let’s look back at the Great Britain a complex...

Unfortunately the criticism is aimed at the wrong target. When things go wrong and it looks as if there were problems with the service trains too, our threadbare rail network seems unable to cope with it. In addition to that I do wonder about how...

It betrays a very peculiar mindset to suggest somebody goes to the trouble and expense of travelling with the aim of being disappointed in order to criticise the operator! On the broader points about 'performance', it seems to me that the heart...

Very often exactly right, but in the case of the WSR a few years ago it was the railway's own management that were telling us how bad things were.
