Modestly, by mainland standards. The rail line goes one way, and that way is south to a single dead end. Less than one percent of working residents commute by train. About four percent take the bus. Gigabit broadband reaches roughly nine in ten postcodes, which is the bit that quietly does most of the connectivity work for anyone who can do their job from a flat above the seafront.
On public transport, the rail story and the bus story go in different directions. Shanklin Rail Station is the southern terminus of the island's surviving line. The line opened in 1864 and was extended south to Ventnor in 1866; the Ventnor extension closed in 1966 and never came back, which is why Shanklin is now the end of the road rather than the middle of it. From here, the line runs north through Lake Rail Station, Sandown Rail Station and Brading Rail Station up to the pier at Ryde, where the boat is. Less than one percent of working residents commute by train, which is what happens when the train, although charming, does not get you to a mainland job. The bus picture is more honest about what an island town can offer. Around sixty-five bus stops sit inside the town's footprint, with services running to Newchurch, Newport, Ryde, Sandown, Ventnor and Winford. About four percent of working residents commute by bus, which is small in proportion but larger than the rail share by a factor of several. The bus is the real public-transport workhorse here, and the fact that nobody talks about it like that is part of how British transport conversations work.
On broadband, the numbers are unusually strong for a town this size and this far from a major city. Gigabit availability sits at about nine in ten postcodes. Superfast availability is at every postcode in the town. No postcode falls below the universal-service-obligation baseline. Mobile coverage from at least one network reaches every postcode, and coverage from all major networks reaches almost every postcode. For anyone whose job is remote-friendly, the connectivity that matters arrives down the cable, and the cable is fine.
The lived consequence of all that is straightforward. About half the working residents drive. About a quarter work from home, which is high for a place this size and reflects both the demographic of the town and the broadband headroom that supports it. About one in eight walks to work. The drive to the town centre runs about seven or eight minutes; the public-transport version takes about twelve. The drive to a primary school is about seven minutes. The drive to a secondary school is about eleven minutes, which is the kind of number that tells you the catchment is wider than the town and not the kind of place where children sleepwalk to the school gate.
For a small island town with one direction of train, a working bus grid and seriously good broadband, the connectivity is what it is: middling overall, weak for anyone whose life depends on a fast mainland commute, fine for anyone whose life depends on a fibre connection and a car.
