At different times, subsequently, authority was granted by the General Assembly for the extension of the line and the construction of branches. In this way the River Division was built, connecting the Wellsville end with Pittsburgh by a junction with the Ohio and Pennsylvania at Rochester, and with the Baltimore and Ohio and Central Ohio, by a line to Bellair. The Tuscarawas Branch was built to New Philadelphia, and there stopped, though its original purpose was to form a connection with the Steubenville and Indiana Railroad. Authority was also given to build a branch from Hudson towards the Ohio and Pennsylvania and any line running in the direction of Columbus. A separate company afterwards constructed this "Akron Branch," or Cleveland, Zanesville and Cincinnati Railroad, so far as Millersburgh. The Cleveland and Pittsburgh Railroad has had a serious financial struggle to go through, but it has come out as an important and prosperous line. It is now working under a consolidation of earnings with the Pittsburgh, Fort Wayne and Chicago, formerly known as the Ohio and Pennsylvania. The Cleveland, Painesville and Ashtabula Railroad Company, now, after several consolidations and changes of title, forming part of the Lake Shore and Michigan Southern Railroad Company, was part of the general plan of the Cleveland, Columbus and Cincinnati Railroad, was built under much of the same influence, and has always been intimately connected with it in its working. The charter was obtained by special act in 1848, and empowered the corporators to build a line by way of Painesville, through Ashtabula county, to the Pennsylvania State line, and to continue their line into that State to any point authorized by the Pennsylvania Legislature. That part of the road extending to Erie, in the State of Pennsylvania, was constructed under the charter of the Franklin Canal Company, passed by the Legislature of Pennsylvania, the 21st day of May, 1846, and amended April 9th, 1849, giving it authority to construct a railroad.
