sentences:  The Delaware, Lackawanna and Western Railroad investigated building a line from Morristown, New Jersey to Mendham, New Jersey (basically the northern half of the RVRR as built), estimating that it would cost $27,000 a mile or more to build, but declined to do so, not so much because of the cost but because it thought that the extension would never be profitable.The chief engineer of the RVRR, John E.V.Melick, on the other hand, stated that the line could be built for $15,000 or less a mile and would be immensely profitable.
