Difficulties, both financial and geological, however, conspired against this section from ever being completed. The first mile above Watnong would prove to be an engineering nightmare and would require the building of a line that resembled a camel's hump, with Speedwell Avenue at the top of the hump. On either side of the Speedwell Avenue "hump" lay a half-mile of rock that would require the use of blasting to obtain an 8% grade, far in excess of any grade on the RVRR.
