The old elevated structure in Jamaica was replaced
quite a while ago now with a two-level subway. The BMT Jamaica Line is below
in the tunnel, and a connection to and from the Queens Blvd. former IND line
is above it, with no interaction between the lines.
In this photo an MTA commuter train on the Long
Island Rail Road zips along its own right of way to the major transfer
point at Jamaica
Station. All these routes provide access in Jamaica to the
new, automated light rail line to JFK Airport.
