Now Hudson was intent on capturing the line to Edinburgh for his empire, and he encouraged the development of railway plans to get there; the route such a line might take continued to generate considerable controversy. There was still ambiguity about Hudson's intentions for the bridge—an easier crossing point at Bill Quay, two miles downstream had been considered—and Newcastle Town Council sought undertakings from him. In addition, he promised a footway crossing; this was apparently not a sweetener to the Town Council, but a commercial decision, expected to bring in £250 a week. The footway crossing was later extended to include horse-drawn vehicles.
