What term describes a vehicle equipped with flanged steel wheels that can travel on both rails and roadways?

• A. Indication
• B. Guard Rail
• C. Hi-Rail Equipment
• D. Fouling Point

Answer: (C)

The concept being tested is recognizing maintenance vehicles that can operate on both rails and roads. A vehicle with flanged steel wheels that run on rails and also uses rubber tires to travel on roadways is called hi-rail equipment. These machines are designed to switch between rail mode and road mode, allowing inspection, maintenance, and emergency work along tracks without needing separate, dedicated rail vehicles or road vehicles. That dual capability is what defines them.

Other terms don’t fit because they refer to different railway concepts: an indication is a signal or indicator, a guard rail is a protective barrier along the track, and a fouling point is a location on the track where a vehicle can foul another track or where occupancy restrictions apply.
