249:(LTSR) was absorbed by the MR in 1912, its locomotives were renumbered into this scheme. It had only two tender engines, both 0-6-0 types, and these became 2898 and 2899. The rest were tank locomotives of varying wheel arrangements, which required the adoption of new number ranges at the end of the tank engine series. In all, the number ranges used by the MR were as follows:
224:
Older locomotives would then be either withdrawn or renumbered into the 'duplicate list' series used for those no longer in capital stock but which not yet completely life expired. These engines were numbered in various series over time: initially they took an 'A' suffix to the original number, then
1033:
A single number without a suffix letter was originally used by the LMS on locomotives that were not of
Midland Railway origin until 1928. Thereafter, it was used to indicate a mixed traffic locomotive. Where a mixed traffic locomotive fell into different power ranges, dual classification was used,
784:
Diesel shunters, which started to appear from the early 1930s onwards, were numbered in the same series as steam locomotives. Originally a series commencing at 7400 was planned, but it was soon evident that this would not provide sufficient space and it was replaced by a series commencing at 7050.
860:. The classification was made up of a number (representing the power output - 0 being low power and 9 high power) and a letter (representing the type of work the locomotive was intended for), e.g. 4F. Over the years there were some modifications to the system, but the basics remained the same.
228:
The GJR and LNWR also named their passenger tender locomotives (all locomotives were named until 1858), and often the same name and number combinations would be applied to new locomotives as they replaced older ones. The removal of names attached to freight engines after 1863 allowed them to be
776:
In 1932, as older locomotives had been withdrawn and new standard LMS designs were becoming more common, it was decided that modifications should be made to the numbering system. In short, all LMS-built locomotives were to have numbers in the 1–9999 series, with pre-Grouping locomotives being
241:
The MR undertook a wholesale renumbering of its locomotive stock in 1907 based on usage, wheel arrangement, power classification (see classification section below), and age, with locomotives of the same class numbered together. The least powerful and oldest classes took the lowest numbers and
764:
locomotives were absorbed in 1930, they were mostly allocated numbers in the
Midland Railway series (appropriate, since the SDJR had been jointly owned by the Midland Railway and many MR designs had been used on the SDJR), though some took numbers in the former LNWR series.
1034:
e.g. 5P4F. From 1953 until 1957 (but remaining painted on locomotives until much later), the suffixes 'FA' and 'FB' were sometimes used to distinguish between freight locos with different load limits due to their braking characteristics on unfitted goods trains.
780:
The introduction of this scheme involved renumbering both new and old locomotives to put them in the appropriate sequences. During the remainder of the 1930s, numbers were cleared for new locomotives by simply adding 20000 to the numbers of old locomotives.
1063:
536:
While the majority of ex-MR locomotives were left unrenumbered by the LMS at
Grouping in 1923, the ex-LTSR locomotives were subject to several renumberings to clear space for new stock, which changed the number ranges set out above.
552:
Many of the constituent companies had numbered their locomotives in a somewhat random way, and the renumbering allowed for all locomotives in the same class to be given consecutive numbers and similar classes to be numbered in
1056:
1084:
557:
These advantages more than overcame the disadvantage of the effort involved in renumbering almost every locomotive and giving them a number that usually bore no relation to its pre-Grouping identity, except for the
221:. Locomotives were numbered in a series commencing at 1. No gaps were allowed in the series, so a new locomotive would either be numbered at the end of the series or would reuse the number of an older locomotive.
1049:
863:
The principal downside with this method of classification was that it did not distinguish between particular classes of locomotive, so many very different types would have been classified '4F' for instance.
768:
New-build LMS locomotives were not allocated any particular numbers, but were fitted into the most appropriate division. The unallocated 13xxx series of numbers were also used for new build LMS types.

Shortly after the LMS was formed in 1923, it developed a new numbering scheme for all the locomotives that it had inherited. The scheme dealt with two key problems faced by the new company:

Within each group, locomotives were numbered in blocks which ran (low to high numbers) as set out below. Within each block, the least powerful locomotives took the lowest numbers.
