Industrial Infrastructure

One of the aspects that I have tried to cover everywhere on my layout is whether the scene is realistic and will it work.  For the latter point, what I mean is will supporting aspects be in place and actually fit correctly into a space.  Take for example, industries that use trucking as a means to deliver materials and take away finished goods. Assuming that the truck and trailer are somewhat correct for the modeled era (example not having a 53' trailer in a 1960's scene), is there actually enough space for the truck to pull in and back up to the loading dock.  I'm always amazed when I see the parking filled with trailers but no visible way to actually move the trailer.  Is there an access road for the trucks to leave the facility or are they apparently stranded since the only exit is over the rails and no crossing has been installed?

Another aspect that I think modelers tend to overlook is what utilities support the industry.  You can follow the same logic and ask do your commercial buildings and residential structures have sufficient utility support.  You may only need a transformer on a pole at a street corner, or you may need several small ground mounted transformers to power each building.  

For an industry, most require a large amount of power, often coming onto the property at multiple locations.  This may mean that they need one or more substations, as well as  multiple transformers as the power is stepped down sufficiently for a building or process to use.  For example, my paper mill has it's own power house, where electrical power is generated from a nearby river which runs along side the mill but is actually just at the edge of the paper plant module.  Since the power house also supplies power to the electrical grid and near by town Spruce River, an electrical substation is located adjacent and in a corner of the property before the electrical lines cross the rail and head away into the distance.  I also have several large transformer situated outside of several of the buildings, as well as electrical infrastructure on the top of several roofs.  In my mind, these little details make the scene "pop" with realism.
