Well enough, given the size. A station inside the town and several more on the same coastal line. Direct trains to London, Portsmouth, Southampton and Brighton. About half drive to work, more than a third work from the kitchen table. The bus is mostly decorative.
Emsworth Rail Station sits in the town itself, on the south-coast line that runs from London through Portsmouth and on to Brighton. The line has served the town since 1847, which is the kind of vintage that means the timetable is well-established and the route is not getting redrawn from scratch any time soon. Nearby stations on the same network include Havant Rail Station and Warblington Rail Station to one side, Southbourne Rail Station and Nutbourne Rail Station to the other, with Bedhampton Rail Station and Rowlands Castle Rail Station filling out the wider commuter belt. About 2% of working residents commute by train, which sounds low until you remember that more than a third now work from home and most of the rest drive.
Buses are present but not central. The brief counts about 52 stops inside the local footprint, which is enough to cover the main routes through the town and the lanes out to the villages. About 1% of working residents commute by bus. That is a useful supplement for households without a car, not a primary commuting tool, and anyone planning a daily journey out of Emsworth is going to default to either the train or the car the first time the bus is twenty minutes late.
Broadband is one of the strongest things on the page. Gigabit-capable connections reach about 87% of postcodes. Superfast is available to every postcode the brief lists, with none of them sitting below the minimum broadband threshold. That is not the bandwidth profile of a town that pretends to be a village. It is the bandwidth profile of a town that has accepted working from home is now part of the housing stock, and the numbers back the decision up. More than a third of working residents do their job from home, which is more than the share who drive to a station and more than the share who go anywhere at all by public transport.
For day-to-day getting about, the nearest town centre works out at about eight minutes by car, eleven by bicycle, fourteen on public transport, and seventeen on foot. That is the geography of a place where the four ways of moving around come out in the same general neighbourhood, and the car still wins on time the way it usually does. About half of working residents drive to work, which is the easiest single measure to take as the truth about how the place actually moves.
Connectivity rates as average on the headline measures, which is the honest answer for a south-coast town with one station and a few roads in. The train works, the broadband works, the bus is for emergencies, and the rest is the car. If a daily London commute is the requirement, the station is on the doorstep and the journey is what it is. If staying put is the requirement, the broadband is the strongest argument for doing so, and the kitchen table is now the busiest commute in town.
