I would imagine distributed traction has helped considerably there, after all multiple units tend to be more resilient in the face of degraded conditions.
We also have to consider the opinion of people living near railway lines - whilst you may go on about how the railway has rights to do all these things, it is not wise to always take up all of your rights. After all the railway only survives become of massive support from the public purse, if you make enemies in the electorate you may eventually find yourself in a position where the taps are no longer turned full on.
Multiple units with distributed drive can cope better with degraded rail conditions, but it doesn't matter if it's a locomotive or a unit when it comes to stopping.
The opinion of people near railway lines changes more often than the weather - people want lovely views, then they want trees, then they want nice fencing, then they want the lovely views again. We can't please all of the people all of the time, but we can try to please some of the people, some of the time.
For every person who complains about trees being cut down, there will be a neighbour who thinks it brightens their garden or gives them a view they've not seen in years, whilst some others will appreciate fewer leaves blowing into their drive or pond.
What always helps is when things like trees are cut down to improve reliability, and we can actually demonstrate that, or when there are improvements, so residents see a new footbridge with a ramp, a longer platform, better lighting, a bridge without a weight restriction and a wider pavement, or in many cases now, they see OLE and new trains, and they can go 'oh - that's why Network Rail did that, I now get a seat on the train in the morning and don't have a 45 minute wait to come home at night'.
