Spoken by someone who doesn't understand what the previous poster actually said... As an analogy, if you're driving your car for several miles at 60mph but then catch up with a lorry (impossible to overtake until a dual carriageway a few miles away) doing 40mph for the last few miles, it would have been smoother, more fuel efficient (environmental factors being a massive thing now) and safer to have driven at 50mph and got closer to the lorry just at the point you were able to overtake. As a Train Driver we drive according to the conditions and route, if we are delayed en route it is not our responsibility to make that time up and nor should it be.
I highlighted a timing issue with a service a few years ago where every Driver was getting delay forms on the same section. One day I entered the section on time and, drove to the limit as aggressively as I felt confident/comfortable with. At the next station I was three minutes late... Timings are not always correct and they don't take into account the difference in performance between different units/locos.
Agreed, but...
To take the example of a route between two cities, say A and E, about 30 miles apart. Linespeed varies but is generally between 75 and 90. One particular empty stock working is booked to follow a stopper over the last bit of the route, so it makes sense to trundle along at a nice sedate pace so that you don’t catch it up quite so quickly. All is well with the world. The problem is that there are junctions along this route, so you can end up delaying something that’s booked to follow you closely as far as B where it diverges. It’s a fine balancing act!
Personally I quite enjoy the relaxed approach where possible, seeing how far I can coast when I know I’ve got time and it’s not going to affect anything else, and braking nice and gently. Conversely, I do enjoy the satisfaction of “making up time” - yes, it might only be because of the slack in the schedule which is what lets me take it easy on a good day, and it’s certainly not pushing it beyond what I’m comfortable with, but I couldn’t bring myself to take exactly the same approach regardless of how late I am!
(As I understand it, too, if that slack’s there because there’s a load of engineering and pathing allowance, if I’m 15L at one reporting point and still 15L at the next reporting point because I’ve taken the same relaxed approach that I normally would, but there’s actually a total of, say, 4 minutes of pathing time in that section, then there’ll be a 4 minute delay generated for me to explain?)
