QUOTE which says its producst comply to the NMRA (National Model Railroad Association) standards.

The NMRA is an association of modellers,in the USA, created way back in the bone age to act as a ''pressure group'' to persuade manufacturers to produce wheelsets and couplers that conform to ''a common standard''.

ie, wheelsets are of identical profile, shape, dimensions, gauge, etc, as everyone else's......same with couplers.

this commonality was to ensure that each maker's stock.......AND track standards..ie flangeway widths, etc..which go hand-in-glove with wheel standards....ran with/coupled to, another maker's stuff.

Such were the numbers of modellers/customers, and equally, numbers of makers.....that the NMRA were very effective at getting everbody to 'comply'....to not do so essentially spelt death to a product.

The NMRA has expanded its standards to encompass pretty much all aspects of modelling....and have been adopted at last by even the UK makers!

It is a big pity that the likes of the old BRMSB in the UK didn't have any influence over british makers in the 1950's....judging by the total mishmash of wheel standards, couplers and track standards being sold to UK modellers...which doubtless spawned the multitude of 'finescale'' modelling standards found within the UK?

Because of the efforts of the NMRA all those years ago, anybody modelling US prototypes [and Canadian, by default] pretty much had finescale track and running straight from the box!

Only in more recent time have the likes of Proto 87. etc emerged, as modellers sought to improve what already existed, no doubt influenced by the likes of Scalefour and P4 from the UK?
