Those models are superb! That 9F model reminds me.
Back in the 1950s, small schoolboy me used to 'bunk' ( trespass) onto the Midland Motive Power depot at Gloucester. It was a superb Railway depot long since destroyed. Fascinating places as was the ex-Great Westen depot only a few yards away.
Whilst being built, those new 9Fs would be used for running in duties down to Gloucester. Saw numerous examples all big, black, brand new and shiny. Looking closely at the driving ten close coupled driving wheels, five axles, the middle axle of the five sets had flangeLESS driving wheels ~ no doubt to allow working on tighter radius rails. Wish I had a camera back in those days ~ poverty stricken schoolboy with limited paper round finances would not extend to such luxuries.
One of the many advantages of being a bit of an aged old git is that I saw most of that stuff you all mention when I was younger. I saw the prototype Vulcan and Victor ( my favourite A-Bomber ) and at Brands Hatch for the F1 Grand Prix back in the 1960/70s, during the lunch interval between races the RAF would come over ~ Red Arrows most years but one year we were in for a treat. A few EE-Lightnings appeared over the natural ampitheatre which is the club circuit and stood those planes on their tails overhead and opened up the throttles .... awresome does not do it justice. And you could do 100mph legally after the event on the way home ~ the cops controlling traffic entering into the spirit of the occasion by using a handkerchief to 'start' the exit from the car parks at Brands. Great stuff ~ imagine that today ... no chance ...
We have not always been a namby-pamby Nation of BMW buyers ...
During my lunch break working in the city, I sometimes took my sandwiches onto the railway stations ~ saw all sorts of interesting stuff and there were both Express Steam and Diesel in those days. On Kings Cross one time, the superb Blue liveried prototype Deltic arrived with a train ~ fabulous sight ~ and the sight and sound those Deltics ( EE-Type 5s) made working hard up the inclines northbound out of Kings Cross I will never forget. There are one or two preserved so the youngsters of today can enjoy those experiences when they use them to again haul passengers on the main line.
Fabulous sights and sounds nearly all gorn forever.
Youngsters today ~ don't know theyze born ...
