Hi guys, I was planning to do some spotting next week at a station along the Thameslink core before the 319's are gone after the peak hour. I previously spotted at City Thameslink back in December and the video can be found here, (https://www.youtube.com/watch?v=m8l798R-OEo&t=119s), but I'd prefer to go elsewhere this time on the core. Where is a good place to spot along the core? I was recommended West Hampstead Thameslink by one of my instagram followers, which has most Thameslink trains running through it, as well as some East Midlands Trains services, and this is one station I am strongly considering. Would anyone else recommend this? Also, should I use my Oyster to get to and from there or buy a travelcard? Ive found that if I've been travelling for more than three hours with no tap out, my oyster resets, charging me the tube fare. This has happened to me a few times, so I don't want to risk it. I will be coming and going out again on a train so getting a Platform pass would be pointless. And lastly, who should I inform that I am spotting on the station? I don't usually inform members of staff because I usually spot at a station for a short period of time, but this time the purpose of my planned trip is to spot, so I will have to tell them, especially with security being beefed up. Thanks in advance!
