All the downtown railroads shifted to Loyola Avenue in 1954.
Downtown Railroads in 1961

The highway at the top is the Pontchartrain Expressway (US90 Business). The expressway leads across the river in 1961, with the opening of the (now-named) Crescent City Connection bridge in 1958. Below the highway are UPT and its tracks, then the Post Office and railroad tracks for that facility. Then other commercial buildings stand at the bottom of the photo. The Illinois Central service yard is below those buildings.
The old Federal Building on Loyola Avenue, with the big weather radar tower on the roof, is visible on the left.
Union Station to UPT
This photo shows no real trace of old Union Station, seven years after UPT opened. The city centralized passenger rail operations at UPT in 1954. They quickly demolished the five passenger terminals operating prior to 1954. Mayor Chep Morrison implemented a “burn the boats” strategy. So, the railroads had little choice but to go along. Prior to UPT, Illinois Central and Southern Pacific operated from old Union Station. Amtrak presently operates UPT, station name NOL. Greyhound Bus also uses UPT.
US Post Office
The Post Office facility originally stood next to Union Station. Since passenger railroads carried the mail from city to city, the main post office was next to the train station. The cars on tracks below UPT carried the mail. They’re parked at the back of the post office. The Post Office (now the US Postal Service) canceled transportation contracts with the railroads in the 1960s. The downturn in passenger rail service is sort of a chicken-and-egg story. The railroads cut back passenger trains. The Post Office shifted to trucks and air mail. Which killed the trains? A little of both.
Additional rail facilities
The Illinois Central RR operated the yard near the bottom of the photo. They staged both passenger and freight cars there. An IC train arrived at the station, then IC switchers pulled the cars out of UPT. They crossed over to the service track for the yard, then parked them.
The city razed much of the land visible here below the Post Office. This made room for construction of the Louisiana Superdome in the 1970s. While the downtown site was one of several proposed locations for the stadium, any changes to the area were just on paper in 1961. The city performed a number of land swaps in the area. This avoided having to buy property outright.
While the USPS facility remains, all of its railroad tracks were torn up during Dome construction. Compare the roof of the Post Office here with the current configuration in a map/satellite program and you’ll see the evolution.
