发明名称 TRACK SYSTEM INCLUDING A GUARDRAIL
摘要 A track system for a railway system includes a base plate configured to be supported on a railroad tie. The system also includes a drive rail and a guard rail. The drive rail includes a head portion, a web portion, and a base portion. The head portion is configured such that wheels of a train car used in the railway system roll thereon. The web portion connects the head portion and the base portion. The base portion is supported on the base plate. The guardrail includes a head portion, a web portion, and a base portion. The head portion of the guardrail is configured to contact the wheels to prevent the wheels from slipping off the drive rail. The web portion of the guardrail connects the head portion of the guardrail and the base portion of the guardrail. The base portion of the guardrail is retained in a support on the base plate. Cross-sections of each of the head portion of the drive rail and the web portion of the drive rail are substantially the same as cross-sections of the head portion of the guardrail and the web portion of the guardrail, respectively.
