This layout seems to have appeared first in 1939. It was either 7mm or 1/4" to the foot and represented the station of the same name on the VR. An article in Model Railroader for 1942, page 198, notes that it was 50 foot long (scale half mile) and was compressed to represent two miles of actual countryside. The article seems to suggest that to make a model railway that reproduced a real location was unusual at the time. It went on to comment on the realistic scenic effects achieved by the modellers.
