Most of my trips to Éire involve my taking a taxi to Manchester Airport on the outbound portion and a train journey back from there on my return. The full price single would appear to be around the £10 mark but its been a while since I purchased one so I am not sure of the price. The reason for that is that I stick with Cheap Evening Returns (or whatever they are called in these allegedly simpler times of Advance/Off-Peak/Anytime ticketing) instead and the whole cost comes to £5.30 (£1.60 as far as Manchester Piccadilly and £3.70 from there to Macclesfield). A recent inspection of the National Rail website reveals that the same price is offered to you for travel between 18:30 and 21:00 so their algorithm must be getting more slick to pick up these things. Another example is the cost of a single fare for travel from Manchester to Macclesfield is usually £7.30 but, on the website, this drops to £3.70 for travel during the same time period. In a time when every pound matters, knowing of this stuff is useful though Northern Rail conductors are good when it comes to supplying you with cheaper fares in the evening time.
