The line now descends by the Kisco, a branch of the Croton and Muddy Brook, to Cross River; thence over broken ground between this strcann and the Croton to the valley which is occupied through the remainder of Westchester, -- a very direct line has been obtained at an expense which must be regarded as moderate, only four structures of any considerable magnitude being required, one of sixty feet over the Bronx, one of eighty feet over the Titicus, one of one hundred and twenty feet over the Cross River and one of one hundred and sixty feet over the Croton at the county line -- a single track with twenty-five feet width in excavations and sixteen feet at top of embankments -- a substantial and permanent track over which passenger trains may be transported at great speed." The road was opened to Croton Falls in June, 1847, and passed through the towns, above White Plains, of Mt. Pleasant, Xew Castle, Bedford, Lewisboro and North Castle, and through, it is said, ninety-seven farms.
