Hi Mark.
If you are interested in some of the other 4-6-0 types, one of my favourites is a relatively recent arrival from Hornby (in fact, I have two of them): the Maunsell ex Southern Railway S15, which was supposed to be a heavy goods engine, but was used as a mixed traffic type, and even found its way onto the occasional express passenger, such was their versatility. The model is very powerful and smooth running.
30830 is one I have heavily weathered, while 30842 is more or less straight out of the box.
The similar looking N15 "King Arthur" (or just plain "Arthur") had larger driving wheels and was intended for express passenger work. Hornby have produced a good many variations on the N15, including earlier Urie style cabs or later Maunsell ones, Drummond 'water cart' tenders, flare-sided bogie tenders and 6-wheel tenders, with corresponding adjustments to the footplate shape. The models run very smoothly and quietly, and will haul a reasonable load. Three of mine are here, with Urie cab and bogie tender (30737,
King Uther), Maunsell cab and bogie tender (30777,
Sir Lamiel, which is a preserved locomotive), and Maunsell cab and 6-wheel tender (30799 ,
Sir Ironside).
Larger still, but probably slightly less successful as a class were the LN "Lord Nelson" class, also from Maunsell in Southern Railway days. This is an older Bachmann model, which has the dreaded split chassis. Nevertheless, these aren't bad runners, only slightly noisier than more modern mechanisms. I have converted two of these to DCC as I considered the running and haulage as being more than good enough to justify the effort. This one is my lightly weathered 30861,
Lord Anson.
Then I have some British Railway 'Standard' types. The Standard 5MT was a mixed traffic class and based firmly on the LMS Stanier Black 5. with updated fittings and fixtures. There were a few different types of tender fitted to different batches. One small batch included Caprotti rotary valve gear instead if the usual Walschaerts type. Bachmann have modelled BR 1B, 1C and 1F tenders on their models. I have three of them, two 'proper' Southern Region allocated versions with ex-King Arthur names (73082,
Camelot with BR 1B tender, and 73110,
The Red Knight with BR 1F tender, not pictured here). Green 73068 has a BR 1C tender and was a Western Region allocated locomotive. The models run smoothly enough but aren't all that sure-footed.
The slightly smaller Standard 4MTs also had a couple of tender variations; mine has the Southern Region specified BR 1B type. The SR ones also had double chimneys fitted, and were reckoned by their enginemen to be as good as, or even better than, the Standard 5s. Both Hornby and Bachmann offer this model. My Hornby one hauls better loads than the Bachmann Standard 5s can manage. There were earlier models of this type from Mainline (avoid, as the mechanism is dreadful), and Bachmann (with split chassis - not too bad, but not up to the newer standards of running).
The BR Standard types tended to be more widespread (less regional, if you prefer) than the pre-nationalisation types. Nationalisation occurred on 1st January 1948.
'MT' stands for 'Mixed Traffic', and the power classifications went from 1F to 9F for freight (the higher the number, the more powerful the locomotive), and 0P to 8P for passenger types. 5MT could also be written 5P5F.
There are many other 4-6-0 types from both Southern and other railway origins, but seeing as my bias is to the Southern Railway / BR Southern Region, the types I have illustrated reflect that. The Black 5s did stray onto the Southern at times, hence my excuse to own a model of one of those!
