Metropolitan Transportation Authority spokesman Salvatore Arena says LIRR and Metro-North ticket vending machines were only taking cash payments for several hours Sunday after a computer network went down about 9 a.m.
Technicians were able to restore LIRR credit-card sales about 2:30 p.m.
Metro-North's machines were restored about 6:30 p.m.
Metro-North automatic payment machines also broke down in most stations on Friday. Arena says that malfunction was unrelated to Sunday's.
