I work for the rail industry & travel on diesel trains almost every day. The modern ones in current use, although powered by diesel, are still very reliant on electronics. The automatic brake (dead mans pedal for the driver) is an obvious one straight off. No electrics = brakes locked on tight & the train is going nowhere.

good point, but what kind of switch is it? forklifts use bog standard mechanical microswitches, these shouldn't be affected by an EMP, especially if partially shielded by the grounded loco body?

Bugger knows mate. I just sell tea & coffee

How many trains have been taken out by ;

1. EMP ?

2. The wrong type of leaf on the tracks.

Waylander

The answer (based on the time I've worked here - almost 10 years) to both your points is zero for each. The only time there is such a thing as wrong type of leaves on the track is when the tabloid papers want a decent headline. The issues with leaves though are 1) dry leaves can jam in the brakes - possible fire risk & brake failure. 2) wet leaves - stops the wheels getting traction & causes wheel-slips. This affects acceleration & can also affect brake effectiveness.
