I really enjoy riding on the Keystone Service Trains. The conductors are always so courteous and friendly. Whenever my mom goes to Philly with me, they are always so helpful to her. My mom is 63 years old. She sometimes has trouble with her legs and that affects her balance. This, in turn, makes it difficult for her to get up and down the steps on the train. The conductors are quick to assist her in making sure that she gets on and off safely. We usually ride #666, a.k.a. the "Triple Six". One of the gentlmen conductors on this train recently retired after 39 years of service.He was always courteous, friendly and helpful and always had a pleasant way of talking to the passengers. This is one of reasons ridership increases, every year.
