Just as any other railmotor the AEC railmotors entered service with matching trailers. These vehicles were 4 wheel in design and were built to be pulled by an AEC railmotor either on their own or in pairs and on some rare occasions 3 trailers were used for higher capacity. Sadly all of the trailers were withdrawn and scrapped with their railmotor counterparts. At times 2 or even 3 trailers were towed by a railmotor on services. These trailers were also used behind the Layland Railmotors.
