And as of this morning, the Delaware entrance is now PRESTO enabled.

Per the PRESTO Twitter account, the fare gates at the main entrance of Ossingston Station are now open: https://twitter.com/PRESTOcard/status/778255602791219201 I used the Delaware entrance this morning, doesn't look like it's quite finished although the gates they had install were powered up.

The entrances for Ossington Station (both the main entrance and the Delaware entrance) are under under construction. The main entrance is unable to sell any tickets or tokens until mid-August, when I assume the new fare gates will be operational.
