1858 Rebuilding By Ramsbottom
In 1858, Ramsbottom redesigned Cornwall almost completely. Little survived unchanged, other than the outside frames and the centres of the drivers. The boiler was now moved entirely above the driving axle, without any notches, channels or tubes, to what would now be regarded as conventional practice.
New cylinders and valve gear were provided, fractionally smaller at 17¼" × 24". Wheel arrangement was now 2-2-2, shortening the wheelbase still further to 14' 10". Ramsbottom also included his newly designed tamper-proof safety valves.
Another minor rebuild in the 1870s provided a typically LNWR style of cab, with a short roof and semi-open sides. She was given her current number, 3020, in June 1886.

Famous quotes containing the word rebuilding:
“... most Southerners of my parents’ era were raised to feel that it wasn’t respectable to be rich. We felt that all patriotic Southerners had lost everything in defense of the South, and sufficient time hadn’t elapsed for respectable rebuilding of financial security in a war- impoverished region.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 1 (1962)
