When looking at the Northern Franchise Document it clearly defines the loading, standing and seating of all units to be operated by Northern Railway. Interestingly it seems that 150s are all to have the same capacity (2car to be 124 seating, 89 standing and 3car to be 194 seating and 135 standing) which suggests there could be a seating change in plan. Even the existing /2s are to have seating reduced from 131 or 149 to 124. This would be strange considering the work which is being carried out already, so maybe a derrogation has been put in place to allow or the work ensures the same capacity even with original seating type being used. 156s are also to be brought into line which again suggests a seating change as the two distinct fleets currently have different seating types and layouts. Further to this, when looking at the electric fleets, 333s, as most are aware, are to have a great deal of seats removed to increase standing capacity (overall unit capacity increase of 91 with 59 less seats and room for an extra 150 to stand) in the West however, the solution on 319s seems to be to reduce seating capacity by 17 and have space for 4 less to stand suggesting more space for each seated individual. Having said that the document doesn't show the different seating capacity of the respective 319 classes pre any refurbishment which there of course is so maybe a shortcut was taken when government produced the document. The document describes the number of seating and standing passengers listed to "relate to the seating and standing capacities upon completion of refurbishment or reconfiguration works in accordance with the obligations of the Franchisee pursuant to paragraph 36 of part 1 of Schedule 6.1 (Committed Obligations and Related Provisions). " and suggests therefore that it must be done!
