Leyden Motor Coach Co. had its beginnings in 1926 as River Forest-North West Motor Coach Co., renamed in 1930 to Leyden Motor Coach Co. Bus service was introduced over some streets already served by Wilcox Transportation Co., but not permitted to carry local passengers. But in 1931, because of complaints about the Wilcox Transportation Co. service, restrictions were lifted against Leyden Motor Coach Co. providing local service. Shortly after, Wilcox Transportation Co. ceased operations. And Leyden Motor Coach Co. emerged as the local operator on all of these streets, except 5th Ave. which was discontinued and is not shown.
Leyden Motor Coach Co. and predecessor River Forest-North West Motor Coach Co. introduced bus service in the following years.
