Is Cullybackey train station an official Park and Ride?

Yes.

Cullybackey train station appears in the official Northern Ireland Park and Ride directory as a rail location. It is intended for people parking before boarding a train, not for buses on the A26. If you travel towards Ballymena or farther along the railway, check the stopping pattern because not every service calls at every halt. For satnav, select Cullybackey railway station rather than a similarly named road or village parking area.
