When Amtrak first took over the passenger trains, I wasn't living in Florida. I had just become a teenager at that time, growing up in Michigan in Ann Arbor, and felt very blessed that we even still had passenger trains on Amtrak day one there.
About a year after I graduated from high school, I was serving my first year of duty in the US Navy. Dad moved the family to Florida in the Tampa Bay area where I currently live. Amtrak had thrice daily service from Tampa Bay to Jacksonville, and the same from Miami to Winter Haven, with only one train going via Orlando to Jacksonville, and the other two trains via Ocala between Winter Haven and Jacksonville. North of Florida, one train went to Chicago, while three others served New York.
In 1979, Amtrak hacked off the Chicago train, and one New York train, and reduced the service frequency to twice daily on all routes in the state. Only one train was left serving Ocala.
After Auto-train went bankrupt, Amtrak picked up this special service in 1982, and it still runs to this very day. This is one bright spot in Amtrak service that has been continuous in Florida.
The Silver Palm was introduced in 1983 as a Miami to Tampa train which briefly resurrected thrice daily Miami to Winter Haven service for about a year, until it was taken off due to state budget problems. During this same period, Amtrak also had thrice daily train service between Tampa and Lakeland.
Although the Silver Palm never went to St. Petersburg, it was during this brief year the Silver Palm was operating that Amrtrak decided to curtail service to Pinellas county, replacing it with Thruway bus service. The long circuitous routing around the north end of Tampa Bay between Clearwater and Tampa took close to two hours. Amtrak built a new maintenance facility in Tampa. Despite a personal plea that I had made to Amtrak CEO Claytor at a NARP meeting I went to in 1984, passenger train service to Pinellas County became history shortly afterwards and has not been back since then.
The New York-Savannah Palmetto was extended to Jacksonville in the late 1980's which restored thrice daily service to New York, but only north of Jacksonville.
Finally, after years of planning and completed track improvements, in 1993, Amtrak agreed to extend its thrice weekly Sunset Limited east of New Orleans to Florida, all the way to Miami. This train was eventually cut back to the Orlando area, as Amtrak had problems with the train running frequently late and could not turn equipment in time for the departures to go west. Also, since Auto-train was using Superliner equipment as the Susnet was, this helped simplify maintenance and equipment pools for both trains at Sanford.
Sharp service cuts came again in 1995, and a short-lived Palmetto extension to Tampa, for about a year or so, with no good connections at any key transfer points doomed that train. Tampa was down to one train, the Silver Star, which ran a split operation south of Jacksonville. Also, the Silver Meteor had its Tampa leg replaced with a thruway bus connection.
A year later, in 1996, Amtrak reinstated and ran thrice-daily service New York to Miami with introduction of the Silver Palm, in a sense restoring the Palmetto service and introducing a night train service in Florida, while the other two remaining Florida trains continued to run through Orlando during the day, and the new Silver Palm train served Tampa and Ocala with its only service during some unfavorable hours for a few years.
Eventually, back in 2005, the Silver Palm was cut south of Savannah again, and the train was renamed back to the Palmetto. To compensate Tampa, Amtrak decided to add a "dog leg" trip to the Silver Star, which in my opinion, has created a phony reincarnated version of the original Silver Palm between Miami and Tampa, as well as the sense that the Silver Star kind of runs as a New York to Tampa only train if it is on time,but Miami only if it's late. This same reouting and dog-leg creation also ended passenger train service to Waldo, Ocala, Wildwood, and Dade City, just like they ended service to Pinellas County in 1983, and replaced it with a thruway bus.
Unfortunately, Amtrak is at its lowest level for frequency of service and routes in Florida since service on its Sunset Limited route east of New Orleans was suspended due to Hurricane Katrina. Nothing has changed since then.
Anybody that can do a "then and now" comparison of service can easily tell that service has been cut since Amtrak's inception within the state of Florida. Even if Auto-train is included, the frequency and number of Florida routes is less than it was on May 1, 1971.
