Many of Moore's car kits were accurate models of streetcars and interurban cars of an earlier era, such as this elegant Niles combine car:
This center door streetcar was based on a "Peter Witt" design.
This Niles freight motor was used to haul packages and light freight. These cars sometimes pulled another car.
This car, an interurban, carried passengers between cities, often at high speeds. There is a small baggage compartment at the right end of the car.
In addition to the electric powered cars, Moore also produced several "gas-electric" cars. In real life, these cars had a gasoline engine which operated an electric generator which ran the motors of the car. They were often described as "trolleys without overhead wires".
