I hope the different viewpoint doesn't mean it's no longer there; I have many happy memories of watching the rather more impressive (ie noisier) SRN6 arriving and leaving in my yoof.
Time for a trip to the IoW now the pier, bus station and railway upgrade work has finished, though I still here of occasional problems with the new trains.
As mentioned the footbridge is still there - my ability to climb it has diminished over the intervening period however.
The catamaran runs hourly on weekdays departing at XX:45. Alternate Island Line services serve the pier head arriving at XX:39. I was aware while I was on the island that it either arrived late and the passengers had an hour's wait for the next or, as on my arrival, the catamaran is slightly late and you arrive on the platform to see the train halfway down the pier.
It is not so bad at weekends when the crossings are half hourly.
