Hydroflex bi-mode unit 799201 passes through Finstock station on 16 December 2025 with the 5Q98 09:43 Long Marston to Swindon mileage accumulation run. I almost missed this, as I was sitting in the car waiting for it to appear on Realtime Trains. When it should have been approaching nearby Charlbury there was still no indication on Realtime Trains, so I was beginning to think it had been cancelled, just like the previous week's booked working. I then happened to look at the map on Open Train Times, and noticed that the route was set through Charlbury, so quickly walked up to the bridge with less than a minute to spare. Only after it had passed me did the Realtime Trains timings appear!
