Rosedale has one decently wide island platform along the Atlantic Branch (which runs from the Atlantic Terminal in downtown Brooklyn to Valley Stream) which is here along an embankment, along wit the Montauk branch, although because of the switches and the fact that there are none west of the station all trains stopping (unless for example a bridgeplate were used) have to run via the Atlantic Branch to Jamaica. This branch isn't it's own for schedules and schedules for this station along with the other two in Queens beyond Jamaica are listed in the Far Rockaway Branch timetable, although some peak hour Long Beach trains stop in the station during weekdays and all weekend service is provided by Long Beach trains offering passengers a one-seat ride to Penn Station instead of requiring them to change at Jamaica because all off-peak Far Rockaway branch service operates to Atlantic Terminal.
For access, at the western end the island platform has two staircases up from either sidewalk of Francis Lewis Blvd's underpass. The farthest west staircase has its own little canopy. The next staircase begins the canopy that covers the station house that is located in the middle of the platform. This station house is brick and decent sized, open only from Monday to Friday from 5:30am to 2pm beneath it. This station house has two separate small waiting areas with a non-public area where the ticket window once was in between. The canopy ends again before reaching the extreme eastern end of the platform where a single staircase leads down to a small pedestrian underpass, on the otherside of this underpass is an elevator up to the platform at the very end of it. The elevator was added in 2008. There is a small canopy over the upper elevator landing that is obviously newer than the rest of the station's canopies. This sidewalk leads to Sunrise highway to the south and North Conduit Avenue to the north between 243 and 244 Streets running between a police station and its parking lot to reach it. Across from the station is a small DOT muni-meter parking lot where parking costs $4.00 a day.
