When Was the D.T. Extended Westward from Pepper to Bluff ?

[NW Mailing List]

Anyone know when the Double Track (east of Low Grade Tunnel) was extended a mile or so westward from Pepper station to the location of a new and remotely controlled interlocking called "Bluff" ? 

Was it at the time Cowan Tower was built in 1914, or was it done when CTC was installed in the 1940s ?
