East Midlands Trains have announced the extra services for the Lincoln Christmas Market this year;

It appears that no extra services from St Pancras are operating this year. I'm also unsure as to what stock will be operating the extra journeys from Nottingham and Sheffield - but I'd imagine it will be HSTs or Meridians. The Newark shuttles will likely be a local unit.
