General Merchandise Run throughs - Then & Now

Back in the late '60s or early 70’s, while I was in my late teens (or a little older), our family home was adajacent to East Bridge JCT in New Orleans, where traffic from the Huey P Long Bridge (2 tracks) interchanged with the NOPB, the IC/ICG, KCS, SOUTHERN, L&N, & other Eastern roads.

At that time, the SP & Southern RR had a lot of trafic between Houston & Birmingham, & it took a few days to get across town from Avondale to NO East…

So, the two parties established a “Run Through” that bypassed both yards in NOLA, taking advantage of the more efficient yard in Houston. They used pooled front end power, & the crew change was @ the east end of the bridge.

The trains routinely had 6 units on the front & a 4 unit helper to get over the bridge. I was led to believe that the bridge in New Orleans was the most significant grade obstacle between Houston & B’ham. The trains were in the 100+ car length ~+ 10,000 tons …

Does anyone else have:

  1. Any knowledge of that operation?

  2. Current operations over that bridge?

  3. Similar operations elsewhere from that time?

  4. Similar operations elswhere today?
