LMS Fowler 2-6-4T
125 examples of the class were built. The last 30 numbered 2395 to 2424 were fitted with side-window cabs. The LMS classified them 4P, BR 4MT. They were the basis for a family of subsequent LMS/BR Class 4 2-6-4T locomotives.
Originally built with a large side opening to cab, which was found to cause problems when running in reverse. Cabs were modified from mid 30s, but final batch of locos(often referred to as limosines) was built with side windows which solved the problem.
After WW2 external steam pipes and new cylinders s were fitted to improve steaming, and both cab versions were modified in this way.
