The London, Midland and Scottish Railway (LMS) had followed the Midland Railway's small engine policy that meant that it had no locomotives of sufficient power for its busy, heavy duty West Coast Main Line. Therefore, LMS designed and introduced the Royal Scot Class 4-6-0 express passenger locomotive in 1927. Originally having parallel boilers, all members were later rebuilt with tapered type 2A boilers, and were in effect two classes. All were withdrawn between 1962 and 1965. Two have been preserved. These are (4)6100 'Royal Scot' and (4)6115 'Scots Guardsman.' No. 6100 'Royal Scot' is owned by Bressingham Steam Museum in Norfolk.

In 1933 one locomotive was sent to North America on a tour.

Sixteenth of Rosebud Kitmaster's releases was their esthetic Royal Scot, engineered to the British scale of TT3 (3 mm per foot, or 1/100) scale. Elsewhere in the world, TT scale is 1/120. Released in May, 1960, this model of an Ex-London Midland & Scottish Railway (LMS) 4-6-0 express passenger locomotive was an impressive niche model. It was also featured as one of three Kitmaster presentation sets: P3: TT3 Royal Scot Set - this contained a Royal Scot class locomotive and four BR Mark 1 coaches in TT3 scale. Short-lived, but critically acclaimed, Rosebud Kitmaster kits of predominately British and European prototypes were, and still are, esteemed by countless model railroaders. Despite its odd scale the Kitmaster Rebuilt 'Royal Scot' was, in its day, an outstanding model, as were all the Kitmasters.

As I have not yet built this kit, I offer these recollections of assembling the model from Mr. Marcus, maker of the Royal Scot for the book Let's Stick Together:
* It makes up into a nice accurate version of the class and is unique as being the only TT loco Kitmaster made.
* It is the only KM kit with metal motion (valve gear and rods) against the plastic motion with the other kits. I suppose it was because the motion in TT scale would be even more delicate than OO. Once painted and fixed it looks fine and is quite robust.
* I had trouble getting the smoke deflectors in the right position. After some sanding and some test runs they fitted OK in the end. It was an important detail as the loco looked completely wrong if they weren't positioned right.
* Transfers (decals) allowed different versions/named locos to be made.

Released for the small TT3 modeling niche, the price was four shillings! It was subsequently reissued as engine 46110 'Grenadier Guardsman,' and 46169 'Boy Scout.' A marketing gamble due to its odd scale, Kitmaster nevertheless spent a great deal of capital tooling for the small market. This did not help Kitmaster's bottom line and to add insult to injury, they decided not to produce a motorizing kit; this decision exacerbated the poor sales of their TT3 line, which further led to lack of interest in the series. Interestingly, it was not until the 1980's that a Royal Scot was released in the popular OO scale.

Kitmaster's Royal Scot is cast in their typical thick black styrene. The model is built with eighty-two parts. The detail and surface molding is high quality but there are many round mold marks. Some are on visible parts. A few sink holes mar small pieces but there is very little flash. Well detailed, the piping and hand rails are unfortunately molded on. While it is relatively easy to carve these off Kitmaster's OO and HO scale models, the smaller TT3 scale complicates this process.

The model is an accurate kit of the locomotive, as Kitmasters are renowned to be.

The valve gear and driving wheels are made to operate. The plastic valve gear and rods are frail in-scale, so Kitmaster included a set of metal rods and valve gear in anticipation of their abortive plan to produce a motorizing kit.

The firebox backhead is detailed but it is the only detail inside the cab. There is no glazing for the cab windows or headlights.

Test fitting suggests a model that may need some filler.

decals and painting

The painting and decals are only for engine 46100 'Royal Scot' of British Railways. This is the dark green livery. Royal Scots were also run in all black with various styles of lining (striping to our American readers). 'Royal Scot' also wore the striking LMS crimson lake livery, which although it was the original livery it received, it did not carry it after being rebuilt (only one rebuilt Royal Scot ever carried LMS crimson lake livery and that was 6170 'Royal British Legion').

Sadly, this is one of the kits Airfix destroyed. This model would make a great centerpiece in a diorama, though limited to 1/100 scale. You will have to really want one as they have been fairly expensive to obtain.

TT Scale--what is it?

TT Scale has been called "the scratch builders scale". This term was first used because TT scaled out to 1/10th inch, or one inch equaled 10 feet. Today it is called "the scratch builders scale" because you have to almost scratch build everything for it, although TT trains are widely available in Europe. Some of these trains and kits are being imported for the modelers who model the European prototype. TT Scale today in the United States has a small die-hard following. It is more popular in Europe and 'Down Under'. There are model railroaders coming into TT Scale all the time, but not as many as we would like.
There has been a revival of TT Scale, of a sort, in that a few cottage industries are cropping up. This may be due to the fact that there are new chemicals and processes that make mass modeling easier for the home enthusiast. Resin casting is one process that has come down in price so that it only takes about $50 and some imagination to produce good looking parts to begin with. Brass etching is another process that can be done in the small workshop. Also, the World Wide Web has made it possible for TT'ers to communicate effortlessly with one another.

British TT is 3 mm scale; that is, 1:100. There is a Three Millimeter Society, a British based society which caters for railway modelers of 3 mm scale. This society was formed in 1965, some years after Tri-ang, a British railway manufacturer introduced model locomotives and rolling stock, in what was then a new model railway scale in Britain, known as 'TT' or 'TT3' back in 1957. The aims of the society are to encourage modelers working in this scale and it produces a quarterly magazine and assists with the production of locomotive and rolling stock kits, components and the supply of secondhand items/spares.*

Highs: Unique prototype. Workable driving gear.
Lows: Molded on railing detail. Eccentric British scale. One livery and marking scheme.
Verdict: For a model four decades old, this kit holds up well. The hand railings will take a little effort to remove if you choose to. This kit can build into a fascinating model with great display potential.

I'm a professional pilot with a degree in art. My first model was an AMT semi dump truck. Then Monogram's Lunar Lander right after the lunar landing. Next, Revell's 1/32 Bf-109G...cried havoc and released the dogs of modeling! My interests--if built before 1900, or after 1955, then I proba...
