LNER A1 Tornado and the new P2 Prince of Wales

 
  t_woodroffe Assistant Commissioner

Woodford,

I can't believe this. You reported on the upgrade of the NE line emphasing the veracity of your commentary based on accurate observation and discussion with the protaganists. However, you continually sprout ill-informed rail fan based rubbish that you do not bother to check through before broadcasting. The VR/VLine DID NOT trash their (considerable) collection of Rolling Stock Branch steam locomotive drawings. The drawings covering new A, D, E, new R and Y Class onwards (including the S Class Pacifics) were carefully catalogued and indexed by the RSB/Vehicles Engineering Drawing Office Manager and others (including myself) and are now safely in the collection held by the Public Records Office, Victoria. They are readily accessible and hard or digital copies can be  arranged.

Your PB sympathisor is clearly a cretin.

Jeepers, no need to get personal.

It is a great thing if those drawings have been preserved. If a project as big as the one being discussed here where to be attempted in Victoria, having access to those drawings would certainly make a massive difference.

I was, at one stage of my career, Motive Power Design Engineer and oversaw the Drawing Office so I take any allegation of drawings being trashed VERY personally.

I will go on record as saying that t_woodroffe is about the best credentialed person to comment on VR design methods and history. I don't blame him for taking these slurs personally. He's had a few to deal with recently.

I would agree with what Valvegear has said.

And the point you are trying to make is what? That a locomotive built to a 13' high outline and a 19 ton axle load cannot pull as heavy a load as one built to a 15' high gauge and a 30 ton axle load?


Yes!!!

It is not a valid comparison and technical superiority cannot be claimed based solely on physical size. American cars are bigger than any other country too, but no-one except Americans buy them because they simply do not fit the infrastructure elsewhere.

For a valid comparison, one needs to put the technical data on a 'specific' basis (like power to weight, or power per grate area). I can refer you to an article in the "Australian Railway Enthusiast" Vol.30 No.2 June 1992, which is also valid to another forum current on Railpage because the article concerned is entitled "H 220 - Australia's World Class Power Unit". In it, you will find that last generation steam in most countries, including USA, England, South Africa and Australia, is fairly similar in specific performance, which suggests that technically they are similar too (only France appears to be ahead of the rest of the world with their demonstrably technically superior (not necessarily mechanically superior) compound locomotives.

For a true comparison you have to consider far more than performance, while performance may have been generally similar other things to consider would be Miles between overhauls, reliability and availability.  Just look at the N&W in the USA a J Class 4-8-4 could do in excess of 15,000 Miles per month or the NYC 'Niagra' More than 25,000 per Month.  While they may be similar in terms of Power to weight or power to grate area, this is one area where the USA were way ahead.
