If one vehicle needs to pass another in an area of limited space, there is not always time for one to wait for the other to back up. Again this makes it necessary for one or both vehicles to be driven over grassy areas as one vehicle carefully squeezes past the other.
If there is a limited amount of space in the goods yard once freight has been unloaded, a driver of a lorry or commercial vehicle may err on the side of caution and drive over a verge rather than risk damaging items unloaded from railway goods wagons.
By creating the muddy areas in logical places over the model landscape it is possible to give the impression that such activities take place on a regular basis. Even if no vehicles are placed on the model railway layout, by creating the effects of vehicles moving around the power of suggestion is often enough to convince the onlooker that this is a location where working activities take place.
This is one of my N gauge scenic model railway layouts. To see more model railway layout baseboards I have designed and built visit my website www.brianford.co.uk.
