In 1925 they were allocated Great Southern Railways (GSR) Class 646 / Inchicore Class J2.[1][2]
The MGWR Class B was an attempt at a more powerful 0-6-0 locomotive than the existing Class L. Like the Class A 4-4-0 which they shared some components they were weight restricted to the Dublin-Galway on the MGWR. They were rebuilt 1916/17 with superheating. On scrapping some of their tenders were givin to Class A locomotives.[2] References1. ^{{cite book| title=The Midland Great Western Railway of Ireland - An illustrated History|last=Shepherd|first=Ernie|publisher=Midland Publishing Limited|publication-date=1994|ISBN=1-85780-008-7|pages=89,130}} {{Ireland Steam Locomotives}}2. ^1 {{cite book|title=Locomotives of the GSR|pages=207|isbn=9781906578268|last1=Clements|first1=Jeremy|last2=McMahon|first2=Michael|date=2008|publisher=Colourpoint Books}} 6 : 0-6-0 locomotives|5 ft 3 in gauge locomotives|Railway locomotives introduced in 1904|Midland Great Western Railway locomotives|NBL locomotives|Scrapped locomotives |
