Im planning a trip with a group of us from Sheffield to Warrington, with all of us traveling with bikes (exact dates and numbers depending on train prices and routes). I don't travel on the route regularly but from what I have seen East Midlands Trains usually seems to have 2x 158s on that route. East Midlands Trains usually have a policy of 2 bikes per train but presumably since they are coupled together there are actually 4 spaces on these trains? Is it possible to book the extra spaces (if they exist)? And do all of the services run as two sets or is it just a peak time thing?
