SEPTA ticket machines
When i was at 30th st the other day i noticed that they had a sign up the ticket machines stating that they were taken out of service. There was no information as to if they would be replaced with modern NJT style machines just that they were taken out of use.
Worse yet if you board at a station that is not staffed you must pay the buy on board rate. While I will admit the machines weren't the greatest they still go the job done.
