39th definitely needs improved pedestrian access. You can only get to 42nd from the southbound platform, which means that if you're heading south on the train you need to walk north to the crossing, cross over, and walk the length of the platform south.
Some people try to cut through the parking lot to Macleod to walk south, but that's a shitty walk over "landscaping" and random concrete, only to end up at the back of a hotel or pawn shop.
I think, bare minimum, there should be pedestrian walkways from both platforms directly to 42nd Ave, and there should be a crosswalk or light at Burnsland Rd and 39th Ave, where the tracks meet 39th. A sidewalk on the north side of 39th Ave the full length of the block to Manchester Rd would be nice, too - there are things to walk to along Manchester Rd: Uncommon Cider, Taiko Canteen, and of course the impound lot!
