CPRR change of ownership and route

From: "Clarence Basso" cbasso@charter.net

Can you direct me to an information source regarding the change of ownership of the Central Pacific Railroad to the Southern Pacific Railroad line in northern Nevada?

When did the SPRR acquire the CPRR right-of-way?

When did the SPRR modify its route west of Lovelock, Nevada, from roughly paralleling then US40, now I-80, to its route via Hazen, etc. and why? ...
