Question: The Shenandoah Valley Railroad had considerably backing from another railroad with what nickname?

The railroad is mentioned as part of the engineering report following the survey of 1846 by Robert H. Sayre, at the time chief engineer of the Lehigh Coal & Navigation Company, where the branch is "described as part of the overall scheme to connect New York Harbor via the Central Railroad of New Jersey to the frontiers via Lake Erie and the Susquehanna River valley. The official incorporated name on the report is the Delaware, Lehigh, Schuylkill, & Susquehanna Railroad Co. where the Schuylkill name is the Quakake Creek climb out of the Lehigh Valley and drop down into Delano Junction which has a descent path to Tamaqua, Pennsylvania in the Little Schuylkill River basin. Accordingly, the Quakake Railroad would become part of the Mahanoy Branch of the Lehigh Valley Railroad in northeastern to north-central Pennsylvania. The Catawissa region was an important source of iron ores and developed into an Anthracite pig iron smelting center, as did Catasauqua, Pennsylvania also on the line of the Lehigh Valley.
