One of the benefits of the Gorse Fox's advanced age is that he is now eligible for a Senior Railcard. This affords him a significant discount on railway travel (off-peak). Examining this for a trip to London next month, GF was pleased to see that with tube and bus travel included it was only £15.50 return, and if GF wanted to tie himself to a specific train, he could get to London for £5.30 and get home for £3.30.
The Gorse Fox can't complain about that! To make things even cheaper, if GF books through Starfleet's Rewards program, he can get a further discount.
