Reading Lancaster and Baltimore Railroad

Hello All I am in search of scouting and survey details concerning the RL&B RR. Primarily looking to verify the start of construction of a Tunnel south of the town of Mohnton,then Mohnsville, in Berks County. The original railway company was the Mohnsville Adamstown Railway which RL&B purchased in 1900. I would appreciate any help from the membership.Everyone I have been told to contact winds up not having any information. I am hoping I am not just beating the tar out of this Dead Horse!
Thanks all! Paul

Thanks Carter The Mohnton website has some of the pictures I have and I have helped to straighten out some of the History issues that have occured with mis-identification. The goog;e link looks somewhat bpromissing though
