I’d like to see the addition of an Estimated Time of Arrival (ETA) in the top left of the screen next to the actual time you’ve suppose to be arriving at the next station. For example, I’m in the Class 43 HST, Paddington to Reading and due to arrive at Reading at 08:17 but on the way I’m held by a red light. Due to this my ETA has changed from 08:17 to 08:19 taking into account slowing for double and single yellows before the red. I’m sure people would appreciate this addition to TSW and it would add to longer journeys knowing you’re behind on time and need to try and make it up from somewhere.
You have the distance to the next stop displayed and knowing your current speed, coupled with your route knowledge of the speeds ahead, pretty simple to make a rough estimate.
