Don Valley Railway the engineering viability of a commuter service on the route and looked at the viability of the project from previous studies. This engineering feasibility study has shown that: Arup recommended that further study is conducted into the following areas in particular: operational arrangements; type and cost of rolling stock; station layout arrangements; track gauge and weight restrictions; sources of funding and patronage estimates. The study can be found on the Don Valley Railway's website. Following the Feasibility Study Don Valley Railway are in the process of developing a business plan to operate passenger services on the route. In order to
