I am wondering what category to use for electrification of an existing railroad. This would involve high voltage distribution from existing power stations to several substations on a 300 km railbed, as well as overhead electrical power along the length of the railbed. I am not sure how to divide this up, since I cannot find anything that really applies. Some guidance would be appreciated. I own the "book", which did not help much in this instance.

It sounds like you need to combine a process model of railroad electrification (and operation) with the eiolca - what is called in the book a hybrid approach.
In essence, you need to identify all the direct inputs to the electrification efforts, and then either estimate their effects from a sector output in eiolca or from some other source. Good luck!

I am looking for EIO for a very specific sector. How do I select this category ?

234920 Power and Communication Transmission Line Construction

This industry comprises: (1) establishments primarily responsible for
the entire construction (i.e., new work, reconstruction, or repairs) of
electric power and communication transmission lines and towers, radio
and television transmitting/receiving towers, cable laying, and cable
television lines; (2) establishments identified as power and
communication transmission line construction management firms; and (3)
establishments identified as special trade contractors engaged in
activities primarily related to power and communication transmission
line construction. Establishments in this industry may subcontract some
or all of the actual construction work. Kinds of establishments include
power and communication transmission line general contractors, design
builders, engineer-constructors, and joint-venture contractors.
