Class 40 water-tank frame

[Neil of Teesside]

I'm considered converting one of my Class 40s into a no water-tank variant. Many years ago I read an article in the Railway Modeller about this conversion, but I don't know which month and year this was published.

Does anyone know what the dimensions of:
1. the water tank frames; and
2. the replacement steps.

Thanks.

If you find out, could you let me know?

I have considered doing a model of 40009 which was the last Vac brake only whistler in service on BR.
that had the tanks removed and the mount hanging down.

I do have a class 40 supplement booklet from a Model mag, I will look to see if its in that.

I think the article you are looking for was in the February 1993 Railway Modeller, starting at page 64. It's entitled 'Detailing the Farish Class 40' and covers nose modifications, roof detail, bodysides, bogies and belly tanks.
Cheers,

Thanks to everyone who have replied so far.

Got the relevant RM. The author unfortunately doesn't give full dimensions. He used 10 thou plastic card with 4 are a trapeziums (2 identical pairs - all are 5mm tall) and the 4th is a square ring. Pair 1: a base of 4.5mm and a top of 3mm. Pair 2: a base of 4mm and a top of 2.5mm. These trapeziums form the arches of the frame with long spindly legs, but no dimensions are given; the author says he used "an appropriately sized drill bit" - I guess it must have been about 2mm or a bit smaller in diameter. The 4 trapezium are glued together and them glued to the square ring (again no dimensions were given other than the thickness the author used 10 thou).

No dimensions were given by the author for the replacement steps. The author used a length of brass strip for the steps superglued to the centreline of the chassis. This position is not the same for all Class 40s so do check the pictures of the loco you are modelling. Make sure you retain the cylinders at the tops of the water tank sides.

Thanks for that neil. Im glad you calculated the dimensions. It was an old article however you are right in mentioning detail variations around water tanks. Also around chassis, the body sides, vents. Grilles, nose ends. Maybe worth finding the book the profile of the 40s js whiteley and w morrison. Oxford publisiing company
