Henry Greenly blueprints

Henry Greenly's 1:1 diagrams for gauge 0 to 2-1/2" gauge, a page from the 1924 Bassett-Lowke "Catalogue B" [image info]

The importance of Henry Greenly to Bassett-Lowke Ltd. (and to the railway modelling community in general) can be seen from the sheer number of sets of model locomotive plans that he produced.

Design modifications

These blueprints weren't just literal copies of the original locomotive plans - as an engineer, Greenly would adapt, rescale and reproportion the designs to improve the stability and track-handling at whatever scale he was working to – while a full-size locomotive's weight makes it unlikely to fall over when taking a bend, the far more extreme track curves used in model railways and the different proportion of weight to track contact area meant that model loco wheels often needed to be out of scale before one even started to consider the rescaling of drive mechanisms and the need to be able to fit commercially-available mechanisms.

Greenly's philosophy was that it was more important for a model locomotive to work well while evoking the look of the original than to be a perfect scale copy that performed badly, so these blueprints and plans allowed modelmakers to build working models steam locos, trusting that Mr Greenly had already anticipated and dealt with most of the potential problems that might beset a model of a particular original loco.

For Bassett-Lowke, Greenly's prodigious output of plans meant that pretty much by default, any loco that was produced in-house by B-L (ie not imported or bought-in from another manufacturer) was likely to be based on a Greenly design.
