The diesel shed has been basically finished. It has been a composition of bits and pieces, a custom job to fit the space. The overall size is not large and will only fit around four smaller main line type locos such as the 44 class locomotives. There is not enough space to devote to a larger shed as this area has to also accommodate a turntable and storage around it.
The shed roof which was made from a station platform kit had to be cut down to size. The shed roof didn't have any ends with it so I fabricated ends using plain styrene and glued on some strip styrene as extra support. Evergreen angle came in handy to cover the edges from the roof to the ends. Originally the end of the kit was three tracks wide and had to be modified back to two tracks wide. It may not be a prototypical building but I think it looks the part, especially when everything around it gets completed.
Along each side at the bottom of the sides I glued a length of styrene, to give some rigidity and it also represented a concrete base to the building.
The whole building was sprayed with a grey paint which was needed to colour up the various pieces of white styrene inside the shed. Once that was done the building was given some weathering using Tamiya khaki drab diluted down with plenty of isopryl alcohol. It is better to make the first paint well diluted and then build up with later coats.
Two sections of fencing were painted white and glued outside the door entrances as a measure to prevent employees going directly onto the running track. Clearances are very tight at this spot.
So the basics of the shed are done, there is still some more enhancing such as some lights over the doorways and internal detailing. I am planning on building an elevated platform between the two roads inside the shed, another day.
