Surely you’re not suggesting that the average road vehicle driver is carrying a comparable risk to the average train driver?
As I said what’s more responsibility.Driving and steering up to 44t gross around 60 ft x 8 ft on the public road among the general public and other road users including pedestrians and cyclists.Or not having to steer a train,on a fixed track,that’s closed to the general public,with features like automatic signal and collision protection.On that note let’s just say that the average train driver doesn’t run the risk of going to prison for colliding with a cyclist while turning left for just one example. 
If I were driving a truck with hundreds of people on board, at over 100mph, and with brakes so poor as to take many miles to stop the vehicle, I might be of the view the risk was the same. The train driver carries the risk of going to prison if he collides, not just because he ran a red light and failed to stop, but ran a red light and failed to stop many minutes earlier.
The train driver has many other aids that road drivers don’t, but in general I’d say that the average person would be taking a greater risk behind the power handle of a train than the wheel of a road vehicle.
It is also not remotely a lesser skilled job than road driving. True, the train does not have to be manoeuvred around obstacles, but it may have to stop in time for obstacles. The driver also has to set the appropriate speed, stop for lights, and ensure that points are set correctly for his route before proceeding - easier I’m sure on a rural line than through Clapham junction. The track is not closed to the public at all, except in some parts just as some parts of the road system are - and there is no general “automatic signal” or “collision protection” system in place.
The driver’s concentration cannot fail for a moment without the risk of an unrecoverable situation (the fact of which may not even be obvious until nothing can be done). The key features of the entire route must be known entirely before driving it unsupervised, and most changes of speed will be done on memory rather than by sight (unless you’re going to drive the train like a pillock, which would put you on a pathway to dismissal if not remedied). And of course, there are schedules to keep. The driver doesn’t even have a radio to listen to, so crucial is concentration.
That crash in Spain a few years ago, where the driver lived but many passengers didn’t, is testament.
To conclude I’d certainly say that a great many more lives rely on a high standard of behaviour from the train driver, which itself is more difficult to achieve than the standard of behaviour required for driving a truck. If a train driver has any lower risk of killing, it is only because of train drivers are selected for their consistently high standard of driving.
