Before buying a set of model trains or Brass HO trains, it is important to understand the space available in the house or garden, so that one can plan the size and layout patterns. In general, a ping pong table is an ideal size, although the structure may have to be stronger to hold trains, structures and other sceneries. One can also use a licensed contractor to build the storage space and display areas or go for a modular layouts available in the market.
Building permanent layouts for Brass HO trains require serious planning of the space and the structures. Once the scale is chosen, the size of the display can be finalized. If a table or similar structure is chosen, careful planning has to be done to keep the track and the accessories within reach. Small scales such as HO or N can be accommodated into peoples den, territory or garage. Apartments can fit in elaborate Z scale models also.
The recent trend is to build large rectangular layouts along the walls of the room. This keeps all the trains and structures within reach and does not take up space in the room. Sceneries can be painted on the walls to merge with the designs of the layout. Typically, two feet wide layouts from the wall in an L or U shape is built with an extension at the end or an island in the middle. More than two feet width would limit the reaching of the trains.
Multi level layouts can also be built along the walls, and can be limited to two sides or even one, if there is not enough space for the trains. A helix or spiral tracks can be used to move the trains along the different levels. This would make the whole display look more complex, but interesting and fun. Constructing railroads for Brass HO trains and model trains and also things like trees, hills, cities and roads need a lot of careful planning and skill too. It is better to refer to various books and other sources of information before building such layouts.
