 As with before, however, trains are occasional and reserved for specialty loads, such as oversized loads and hazardous materials, which will be banned from the tunnel.It was also stated that the trains, which will be able to go up to 30 mph on the newly renovated line versus the old limit of 5 mph, 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, in the future a passenger station may be added.
