However, trains are occasional and will be reserved for specialty freight, such as oversized loads and hazardous materials, which will be banned from the tunnel. As well, trains will be able to travel at up to  on the newly renovated line, in contrast to the old limit of , and so will be able to cross Biscayne Boulevard in 90 seconds. The current plan is for the line to be strictly for intermodal services, with the project including a rail yard and station at the port. However, a passenger station may be added in the future.
  The cost of restoring the rail link between the port and the Hialeah Railyard was estimated at $46.9 million, $28 million of which was applied for through a federal grant in 2010. Later that year, a grant of $22 million was awarded for this project, as well as to build an on site intermodal rail yard at the port. During the 2000s the percent of Florida East Coast Railway's business has increased from around 60% to around 80% intermodal freight. However, this was partially due to a decrease in other freight traffic caused by the 2008 recession, which reduced the number of trains, many carrying rock aggregate used in construction, from about 20 to 14 per day.
