Watch train on departure boards
Each departure column now has a Watch train link beside Share train—it opens the same highlight link and keeps the train in view when the board refreshes.
What changed
Departure boards gained a Watch train action next to Share train. It navigates to the same ?train= deep link used for sharing, highlights that service, scrolls it into view, and re-focuses it after each automatic or manual board refresh while you stay on the link.
Why it matters
You can pin a specific departure on a busy board without copying a URL—handy when you are already on the station page and want the column to stay highlighted as times update.
Who benefits
Passengers tracking one train on a multi-column board, and anyone who shared a train link and wants the same highlight behaviour from the board UI.

Technical details
Watch train uses the same ?train= URL parameter as Share train. While that parameter is present, the matching departure stays highlighted and scrolled into view, including after automatic or manual board refreshes.
