I've regularly used the route since the early 70's and in the past 40 years it hasn't really changed that much and where it has those changes are frequently quite obvious. Platforms have been extended to accommodate larger trains and the stations are more automated but the old ticket offices, waiting rooms etc are still quite evident. The yard to the west of Woking north of the mainline has greatly shrunk while that south of the line now handling gravel/sand has expanded. At Basingstoke the overnight parking/cleaning facilities to the east have been added in recent years. Fortunately there has not been that much modern building close to the track other than close to Woking and Basingstoke, plus the odd glimpse of the M3. It will be interesting to see your efforts develop, good luck. Peter
