I am aware that this has been reported, but I believe I know what is causing this issue. The culprit is AWS on the class 395. If you turn on AWS before departing Faversham, it keeps thinking that the signal is red when it is actually green. To avoid this bug, you need to not activate AWS and it will let you pass the signal without an issue. This does not occur on the class 375. This specifically happens only at Faversham. So once you get past the signal, you can then activate AWS and go on with your trip.
