Progress
Victorian train engineers had no electronics (no thermionic triodes, no semiconductors, let alone the power semiconductors used in trains today). They had no computers to help design or to run their trains, little of our nearly 200 years experience of railways, no software for simulation, no software on board or to help manage train movements. Yet they could get their trains running again faster than we can now, in the 21st century? Maybe ours should carry a load of coal for backup to these "advanced" systems that can become confused.
