As a terminal station, it features a large park-and-ride lot for commuters, and with an average of nearly 1,600 passengers per day it is the second-busiest station on the N Line (after Union Station). Northbound N Line trains terminate on one of two tracks, from which they return to Union Station. These tracks extend past the end of the station to allow for terminating trains to lay over, and the overhead catenary system (OCS) was installed such that the line's eventual extension would not require the relocation of any equipment.
The N Line was constructed along a former Union Pacific right-of-way. This right-of-way extends far north of the station, into Weld County, and eventually terminates in Frederick. The track north of Eastlake/124th is currently disused, although a bicycle trail was constructed along it. The right-of-way narrows to a single track immediately south of the station as it was not double-tracked during the N Line's construction. With the exception of a short segment further south in Thornton, N Line trains departing from Eastlake/124th remain on a single track to Commerce City/72nd station.
