This topic has been discussed multiple times on this site.
When looking favorable at the "Dixieland's" route, it should be remembered that this was the first of the "fast three" to die.
To summarize previous discussion:
The fastest and most popular, the City of Miami through Jackson TN, Birmingham, and Columbus GA is no longer possible. Critical segments of the route have eitehr been abandoned or become slow speed short lines.
The South Wind route, which became the Amtrak Floridian's route would need major work between Chicago and Indianapolis and between Montgomery and Waycross GA to have a decently fast schedule.
The Dixieland route, while all in place and all with CTC signalling and higging the most centers of population, although missing such places as Indianapolis and Louisville in favor of Evansville IN, is very congested with freight, very curvey across northern Georgia and with reductions in Superelevation on many curves could not support the speeds of the past, nor given the current realitiies where the train could not be "given the road" there is no way the former schedule could even be approached.
George, I think two things may have contributed to "my train', the Dixie Flagler/Dixieland falling first.
One, the fact that the Flagler was slower to run all streamlined sleeping cars, as noted per my earlier post. The City of Miami and the South Wind only suffered that anomoly one or at the most two winter seasons. The Flagler had some lightweight sleepers of course but it was not until it was re equipped and renamed the Dixieland 12/54 that all its sleepers were streamlined.
Secondly, the winter season New Royal Palm gave more daily competition than might be thought. It was all streamlined and daily and from Chattanooga and Atlanta to Jacksonville and Miami was fully as fast as the Dixie Flagler/Dixieland. Noted in my earlier post, both the SW and the City served Birmingham and the SW and the Flager both served Nashville. But the additional competition from the New Royal Palm on its faster winter schedule seemed fairly intense.
