Whaaaaaaaaat? Yeah, the in and out of the tunnels makes it fun no? Plus the loops with various freight trains being overtaken, the randomness of whatever has been dumped at the old oil terminal at Micheldever station and then the sun shimmering off a misty morning over the River Dever. If you're lucky you get to see teeing off at Test Valley or a wicket being taken at Oakley CC. Deffo more interesting than say further up towards Farnborough (well, I think so).
I like the wide open views of rural Hampshire on this section, particularly in the Springvale/Kings Worthy area, and even more so, the stretch leading up to Micheldever (from the south), passing Micheldever village.
North of Micheldever is less interesting, though, with a lot of cuttings and just occasional nice views.
And to answer the original question (sorry, post automerged):
It's not my local line anymore but it's the line I used to commute to school in the 80s, so probably counts for something: the Portsmouth Direct.
However I will cover the whole line from Havant to Woking, not just the section I used at the time.
Most interesting parts:
Rowlands Castle to Petersfield - some really nice views of the Downs, both sides of the tunnel.
Grayswood area to Witley - nice wide open views of the countryside
Shalford Junction area - likewise
Less interesting:
Havant to Rowlands Castle and Petersfield to Liss - views rather restricted
Worplesdon to Woking - likewise
Formerly interesting for the sound effects:
Haslemere to Milford northbound in the 1980s, and also just south of Shalford Junction. The almost tuneful or rhythmic roaring rails and jointed track sounded like a "Commuter Symphony"...
