Since I was given my first proper OO Duchess of Atholl in 1949 there have been two things which foster the discontent in me! These are valve gear and chimneys (or funnels as I prefer).
The over thick wheels and the ridiculous bends could be excused away but my bugbears no. As nippers we could identify any class at over
1000 yards by it's funnel and the valve gear made it into the super complicated machine which we worshipped.
I have news for you all. When I was a pupil of the CM&EE at St Rollox in the 50's we always called what you English guys call a chimney, a 'funnel' This is a perfectly respectable locomotive engineering term. Don't let's start some new myths, we have enough of the existing ones. I even designed a funnel once when I was in the DO at the NBL later on in my training (SAR Class 25, if you must know). The thing the smoke comes out of is a funnel. The Scot's have a saying 'Lang may yer lum reek, wi' ither people's coal'. 'Lum' is another common term for a funnel also in common use on the footplate.
I'm glad to hear that someone else has a valve gear fetish. I'm a fellow sufferer and have regular bouts of revulsion at the efforts of modern RTR producers (both Bachmann and Hornby) who will persist in putting the Walschaerts gear return crank on backwards on one side of the loco. Modern RTR is just so good that this idiotic fault should not recur time and time again on new models, but it does. I guess the LCL's (little chinese ladies) don't know any better but it makes you aware of the poor QC being done these days. Back in Margate times Hornby always got it right.
