Many layouts are made to mostly run trains. That is to set them going and sit back and enjoy. Most layouts that are designed to run have loops of track without many or any switches.
Most display layouts in hobby shops, malls, department stores of the fifties are this type. With proper design and multiple loops, that often hide the train routes from view some of the time, these layouts can be very interesting and can run with little or no attention of the train engineer.
These layouts can keep visitors amused for an hour or two, often about the time visitors have and get lots praise and enjoyment. A running layout as a home layout often can cause a loss of interest by the engineer in a short period of time unless improvements or additions to perk interest are often made.
Other layouts are designed to be operated. They are complicated and involve lots train routes, multiple trains operating, sometimes on the same loop and allow trains to switch between loops in conventional control. These layouts can have numerous operating accessories like cattle cars and pen, milk cars, ice station, log loads and unloaders, barrel loaders and unloaders and even operating turntables and round houses. These layouts require much engineer attention and often attention of two or more operators.
Operating layouts are a good choice for a home layout to have lots of action and engineer involvement and can keep interest in the layout for the long-term. An operation style layout can be operated as a running layout in most cases if loops are included to allow low attention by the engineer.
Do you prefer to run trains or operate trains? Or both?
