RRVs are modified versions of road vehicles, in this case excavators, which retain their normal wheels with rubber tyres. They are also fitted with additional flanged steel wheels which can be raised and lowered as required, enabling them to run on rails. The flanged wheels are free-rolling with propulsion on the rails being provided by the conventional tyres.
The SVR has three of these similar road railer excavators. Like the [[Komatsu 160 Road Railer | Komatsu 160]], these road railers can be used with various buckets for excavating and moving spoil, or with a flail head for clearing trackside vegetation.
