The underground station has a centre loading platform that can accommodate two 5-car LRT trains at the same time, with one train on each side of the platform. At just under , the underground platform is narrow by current Edmonton LRT design guidelines. Access to the platform is from the concourse level by stairs and escalators located at each end of the platform. The concourse level is part of the
Edmonton pedway system. The system control centre for the Capital and Metro lines is located on the Churchill Station concourse level. The
Edmonton Transit System Customer Services centre, complete with lost and found, was also located in the station before moving to
City Hall in February 2013, then to the
Edmonton Tower in early 2017. At one time, windows allowed pedestrians to view the control centre, but these were removed in 2008.
Public art The underground Churchill station includes two pieces of public art. The first,
Ridden Down is an abstract sculpture using welded steel that was installed in 1996. The second is a mural entitled ''New Year's Eve''. ==Lines==
