A view of the prototype of Kevin, showing a gypsum train and the loading facility. These loaders were perfectly matched for 4-wheel wagons, but with the advent of bogie stock loading is now carried out by front-end loader. The DBT module Kelvin is based on this prototype. The track plan is a replica of that at Kevin in the 1970s, as the operating track at that time simply consisted of a loop, a dead-end siding for gypsum, another dead-end siding for salt, and a wye.

Another view of the prototype at Kevin, showing the salubrious air-conditioned station offices! Note the mounds of salt and gypsum surrounding the tracks. The train in this view is the salt train, standing on the wye. By now the salt siding had been lifted, and salt was loaded by front-end loader with the train stretched out around the wye. The model of Kelvin includes the salt siding, but for space reasons the wye is only partially present. This in fact is the way the station was operated after diesels came, but prior to the advent of bogie wagons, and the wye fell into disuse. After the larger wagons appeared the whole train is reversed using the wye, as shown here. The wonderful facilities pictured in this view have not been modelled, rather a "proper" station building as befitting the major revneue earning station on the Dutton Bay. John Dennis
