The St. Louis Gateway is an N-scale layout representing operations on the Terminal Railroad
Association of St. Louis (TRRA) around SH Interlocking and Madison Yard during the late 1980s.
The operations simulate traffic patterns through a major interlocking tower, SH Interlocking in
Madison lL. During an operating session, the SH Tower operator will control the movement of
about 50 trains from 5 different mainlines. About half of these movements are switching transfers
from many different railroads in the St. Louis area (5 staging yards.)
