Railway updates on my Edwardian blog

Just being a teensy bit 'picky', but the GER tank locomotive is an 0-6-0T.

J69 was an LNER class designation - the correct GER one for this particular type of 'Buckjumper' was S56, of which only 20 were built.

These were the last of the type but the only ones to be built with wide tanks and cab, and had the boiler pressed to 180 psi. They were distinguishable by the 'keyhole' cab, having an equal width cab opening either side of the door. All others of the R24 and R24R(ebuilt) types had a wider opening towards the front of the cab.

Got to love the NER Electric shot thanks for posting.

Thanks, one of my favourite photos so had to post that one, personally I think it sums up the Edwardian/WW1 era perfectly - modernisation, war, and the growing role of women in the workplace

Thanks, apologies for the mistake on the wheel designation - will get the post changed too, I took the information from the NRM display board next to the exhibit as GER isn't my strong point, but by the time you read this hopefully it will be correct

I'm at a workshop this weekend, as are several of the NRM types - I'll mention their 'terminological inexactitudes' at some convenient point.

I note that you've a link back to this LNER info website - where the page describing the J67 and J69 classes also has a glaring error - whoever wrote it combined the GER S56 with the LNER J69 to produce GER class S69 - which is the B12! (4th paragraph).

I'll report this post, so that Richard can correct that sometime...

Thanks Mike - more typo than "glaring error" I think. I'll fix it.

Ay up!

Ah, the ol' flying fingers eh?

Yours

Mr Typo!

Oh dear, don't propagate that hoary old myth. Ever plotted the data that the recorder didn't actually consider worth publication? He was right to have his doubts as there is a very noticeable 'bump' in what should be a smooth acceleration curve where speed suddenly jumps up over 2 mph above the expected curve. On that basis various 'experts' have made astoundingly accurate claims like 102.3mph. Apply a data plotting programme' curve fitting tool and you get something in the 98mph region. The top edge of the error bar pushes over 100 mph, but the resolving power of the recorder's technique is pretty coarse leading to large error bars.

Consider what he was doing. Operating a recording stop watch, counting 22 rail joints for quarter miles, scribbling down the succesive times while still counting the joints; any short rails and points all tend to make for short quarter miles, and then there is the actuation error of the stopwatch. No way to get a precise enough result when the speed was somewhere near the 100 mph mark. (In terms of amateur observers using stopwatches, the only 'over 100 mph' claims that can be taken seriously are where the speed actually reached 110mph. Basically you had to be behind an A4 to be sure of getting a definite 100mph.)

Your blog would be far more interesting if it were contrarian: frequently proposed as the first UK locomotive over 100mph but the claim is invalidated due to inadequate data.

Ay up, Hatfield!

Plus don't forget that Rous-Martin was in the employ of the GWR at the time, so it's hardly an unbiased account. After all he who pays the piper calls the tune!

Personally, I don't believe the 100mph claim either. The speed curve suggests that either a banking engine (hitherto unknown to history) suddenly opened up or City of Truro dropped off a cliff!

[Rlangham]

I decided to mention the 100mph claim as that's what City of Truro is famous for.

Hopefully less controversial is my latest post - http://electric-edwardians.blogspot.co. ... -1916.html - a 1916 Midland Railway Motor Car Van

Ay up!

Interesting. Earlier than I thought motor car vans existed.

Couple more - one was brought on by Micky's topic about Quintinshill

Nice pic i have one of a sentinel railcar at the same spot.
