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]
