Shopping List of N&W Information

[nw-mailing-list at nwhs.org]

Here are some things we need to establish:

1.  When/where was the electric track circuit first used on the N&W?

2.  When/where was the first installation of an Automatic Block Signal System on the N&W?  When/where were "coded track circuits" first used on the N&W (it was sometime in the 1930s on the Norfolk Division.)  We could also use a chronology covering all installations of Automatic Block Signaling on the N&W.

3.  When/where was the first interlocking installed on the N&W?

4.  We need a complete list of all "interlocking stations" (i.e. towers or cabins that controlled interlockings) on the N&W.

5.  When/where was the first remotely controlled interlocking installed on the N&W?  (I think it was at "NR" North Roanoke, in the early 1920s, remotely controlled from "UD," the Shenandoah Div train dispatching office in the old Park Street building.)

6.  When/where was the first use of a pneumatic switch mechanism on the N&W?

7.  When/where was the fist "all electric" (or "all electro-pneumatic") interlocking constructed on the N&W?

8.  When/where was the last purely mechanical interlocking retired on the N&W?

9.  We need a chronology for the installation of CTC on the N&W.

10.  We also need a chronology covering the installation of double track on the various Divisions.

11.  And finally, we need to spike down the dates for the establishment and dissolution-or-merging of the various operating Divisions (such as the "Central Division" and the "V&T Division," etc.)

Some of these questions are probably answered in the old N&W annual reports.

<< PS to Ken Miller...  I shall expect to have your detailed report, answering all particulars indicated above, by the end of the present month.  -- /s/ R.H. Smith >>
