Efficiency is the only way forward! We are strictly moving away from these outdated, soot-covered steam engines. It’s time for the era of Diesel and Electric if we want to actually stay in the 20th century.
Am I the only one who thinks clinging to old steam technology is just a waste of the budget? If @Sir_Topham_T hat thinks he can just keep his little "North Western" steam fleet running forever without consequence, he's got another thing coming.
