Arriva are now likely to appear on rail replacement more often than in recent years, most likely for Southern/Thameslink, owing to some significant background work by local staff. It is only being staffed after all regular duties are covered (subject to on-the-day changes).
I'm advised that for next weekend, a selection of vehicles should be out as follows:
Saturday 24th:
Gillingham: Three Bridges to East Grinstead
Sunday 25th:
Gillingham: Gatwick to East Grinstead
Northfleet: Tonbridge to Redhill
Tunbridge Wells: Three Bridges to East Grinstead.
