Per a request from RATTLER21, here are some shots of my Borden's Dairy with some construction commentary.
Here is an overall shot. The dairy building is made of two Walthers Brook Hill Farm Dairy kits.
It is served by a rail spur that enters from the left side. All pallets on loading docks are made from scale strip wood. I built a jig to make the pallets (see next picture). Fence is also made of strip wood.
The chimney is a Walthers HO kit - Brick Smokestack. The silver storage tanks is from an old HO scale Campbell Scale Models kit. It serves as an fuel oil storage tank for the dairy. This provides additional switching traffic for the dairy - a tank car to deliver oil. I have found that a lot of HO scale models can be "re-purposed" for O scale use.
The fire escape is modified from a Tichy Train Group fire escape. I think that details are important to "sell" a scene - track bumpers, scale, milk cans.
The Borden sign is an image of a real sign I found on the internet. I printed it on cardstock and attached to plastic supports.
The water tank is a modified Kober Models HO scale water tank (kit number 128). All the roof top vents are also HO scale from Walthers Reef Detail Kit (933-3733). I use these HO roof details a lot. They look good on O scale buildings.
The parking lot is made of Plaster of Paris.
I cut the loading dock doors out of the building to create a partial interior view. The Borden's milk crates are made from an image I found on the internet and reduced to O scale. They are printed on cardstock. The overhang is made of strip wood and corrugated metal.
