745s
Can someone explain why a 745 has carriage numbers 312xxx-322xxx-346xxx-344xxx-342xxx-302xxx-301xxx-341xxx-343xxx-332xxx-426xxx-413xxx
For a start, why two 4xxxxx vehicles? 413xxx follows the numbering of 700s, 426xxx follows the numbering of 707s
Then, I recognise two 30xxxx but then three 34xxxx vehicles in one half set and two 34xxxx vehicles in the other.
Just seems unnecessarily complex. Is there some logic to It?
345s vs 387s
Pretty logical set of numbers for these 3401xx-3402xx-3403xx-3404xx-3505xx-3406xx-3407xx-348xx-3409xx but why is the carriage position at position 4 rather than position 3 like on a 387 which is 421xxx-422xxx-423xxx-424xxx.
Is this somehow connected to an expectation of multiple fleets of 387s compared to only one fleet of 345s?
710s
The 710/2s are 4321xx-4322xx-4323xx-4325xx recognising that there will be some five coach units. Why are 710/1s 431xxx while 710/2s are 432xxx?
80x units
The numbering of these doesn't provide for similar cars to have the same numbers.
801101 is 821101-822101-823101-824101-825101 but 801201 is 821201-822201-823201-824201-825201-826201-827201-828201-829201 so on one type of unit 825xxx is a driving car and on the other 825xxx is a centre car.
I get that there is a new framework for carriage numbering which uses 6 digit numbers and has a structure but why is there so much inconsistency?
Is there something I have missed when the full EVN is considered?
