Yes, I believe it is the 0735, 1320 & 1900 ex Dublin and the 1035, 1605 & 2136 (2128 on Saturdays) ex Belfast (Mon - Sat) and the 1000 & 1600 ex Dublin & the 1305 & 1905 ex Belfast on Sundays.
By the way, does anyone know if the 06:35 ex Newry and 17:13 ex Pearse will be affected during the July and August line closure?
