Expertise is required

The story of the shed code system is as follows:

1. It was introduced by the LNWR in 1863, and applied to its own system
2. After the grouping in 1923, the LMS extened the system. The ex-LNWR shed codes in the LMS's Western Division didn't change significantly, but the rest were extended to the other divisions of the LMS (i.e. Midland Division (i.e. ex-MR), Central Division (i.e. ex-LYR) and Scottish division.
3. After nationalisation in 1948, BR then adapted the LMS system to the rest of its regions.

There was minor reorganisation over time. However, this is basically why the LNWR sheds have the lowest numbers in the BR system, because they had the lowest numbers in the original LNWR system.

It would be helpful if people took this on good faith and didn't start screaming "citation needed". I don't pretend I'm an expert but I am certain of the above facts, which are supported in the references. Tony May (talk) 03:00, 15 October 2018 (UTC)

Tony May, please stop adding this information. The London and North Western Railway used shed codes, yes; but so did the Midland, the Lancashire & Yorkshire and various other railways. Crucially, nothing in the reference says that it was the LNWR numeric system that was developed into the LMS number/letter system. Consider this: how do you get from 1 Camden, 2 Willesden to 1A Willesden, 1B Camden? Please see WP:SYNTH. --Redrose64 🌹 (talk) 19:47, 15 October 2018 (UTC)

@Tony May: We've all had the "I'm sure of this" situation but we have to go with what the sources say and the LNWR Society doesn't support an assertion that the LNWR system was extended into the LMS system. Here's another source that says the system was expanded from the MR shed numbering system including the alpha and numeric style. As the book was written in association with the Midland Railway Society it is as reliable as the LNWR site and it rebuts your "fact". Either could be right and the truth is probably somewhere in-between but considering the preponderance of ex-Midland personnel at senior levels with ex-MR man J H Follows as Chief General Superintendent with the Superintendents of Motive Power answerable to him rather than the CME suggests to me that it is more likely that ex-MR practice was expanded in organisational matters rather than ex-LNWR practice. There's no doubt that Western Division shed got the lower numbers but that's not proof that LNWR practice was followed. Nthep (talk) 21:33, 15 October 2018 (UTC)

List dates

Looking through the LMR list I find it rather confusing because LMR completely recoded in 1963 and yet the list lumps pre- and post-1963 codes in one list. Is it reasonable for me (or someone else) to split the LMR list into two, an initial list for the pre-1963 codes and a second for the post-1963 codes? And possibly the same for WR 84, which was affected by the LMR reorganisation? Rossh1 (talk) 11:06, 21 October 2020 (UTC)

It probably needs new columns rather than more tables. Geof Sheppard (talk) 16:11, 21 October 2020 (UTC)

The 1963 recodings were because of a major change in the regional boundaries. Most regions both gained and lost territory, and the LMR, having mutual boundaries with all the others except the Southern, experienced the most changes. It took the opportunity to resolve overlaps - for example, in the Birmingham/Wolverhampton area, the ex-LNWR sheds (in group 3 until 1960, then group 21), ex-MR sheds (formerly in group 21) and ex-GWR sheds (formerly in group 84) were all placed together in group 2. But the basic plan remained the same - groups 1 to 12 were the former "Western Division"; groups 14 to 22 were the former "Midland Division" and groups 23 to 27 were the former "Central Division". --Redrose64 🌹 (talk) 21:08, 22 October 2020 (UTC)
