All:
I have found the following info about Locomotives on Trains #5 & #6 out of Dearborn Station:
Using 59 sheets that have been scanned between January, 1966 and October 5, 1967 (638 days) and from the 136 of a possible 365 sheets from the “1965 drawer†at WHQ Yesterdays openhouse (03/03/12)I found the following:
On 43 (of 68 possible) sheets from about June, 1965 until before September 08 a single 20 Cass (RS2s) Engine (#23) powered #6 from Shops to Chicago and #5 back to Shops on most days. On the Southern Division ( Shops - Louisville) 200 (F3s) Class engines were always used. Occasionally two 200 class engines were used on the north end This was apparently on days when one or both trains were heavy on the Northern Division.
Otherwise until September 23, 1966 two (200 Class) were used presumably back to back. The numbers were different on #6 (in) and #5 (out) indicating that they would not have been turned.
After September 10 until sometime between October 12 and December 26 either 2 -200 Class (F3s) or single 500 Class (C420s) was used. Single 500 Class (#501 or #502) was used. October 1 to October 4 trains #5 & #6 were annulled. They did not appear on the train sheets thereafter.
The following General Order was issued:
GENERAL ORDER NO. 1717
Lafayette, Indiana September 27, 1967
TO ALL CONCERNED:
Effective October 1, 1967 the schedules of Trains 5 and 6 on First, Fourth and Fifth Slub-Divisions, are annulled for the duration of Timetable No. 17.
Signed R. D. Tigar, Gen. Supt. – Transportation
Also as a footnote on December 26 engine 501 ran (passenger?) extra Shops to South Hammond with the Purdue Band Special. (Inroute to the Rose Bowl?). Train sheets between January 1and 23 are not present to show a possible return trip.
