Do I need to pre-book? Expand Pre-booking is advised as we manage capacity onboard our 'Seaside Special' and 'Yorkshire Explorer'. When you travel on these services you have a set departure and return time and are subject to availability. To help us monitor capacity, we are asking all our visitors to pre-book their tickets where possible for our Pickering to Whitby or Whitby to Pickering trains. Tickets can be purchased on the day, and shorter journeys are available, subject to availability.
