Cuba

"If you decide to go on the train adventure, it’s important to know that tickets cannot be reserved on the Internet. The bookings have to be made in Cuba at train stations or the state sales points (Viajero). It is advisable to ask about the closest sales point in the city. Under certain circumstances it is possible to avoid the way to the train station, as is the case in Santiago de Cuba. Now bookings can be made for the way there and back. 

Since foreigners have to pay for journeys on the main routes in USD, they usually get the tickets at short notice. Generally, it is possible to get a seat the day before or even on the day of departure. Anyway it is better to be safe and therefore to reserve a little earlier." - https://cubaify.com/getting-around-cuba/trains-in-cuba/ Link includes time tables and fares.

French Guiana

"French Guiana never had an established rail system, though a train does exist within the Guiana Space Center. Buses are the main form of transportation to get from city to city or around Cayenne. Several lines serve the capital, while minibuses provide transfers between major areas. Buses follow a fixed rate system and you will be asked to pay the full amount even if you are only traveling part of the route." - iexplore
