Home <-> Walk <-> train(euston) <-> walk <-> tube <-> walk <-> work

Time required if everything work correctly

~ 1h 10m to work

~ 1h 30m from work, (more since you dont want to miss the train)

Now, a single cancelled/missed train for me is +30m, happened at least once a week due to faulty train etc.

In addition, these things happen all the time:

Is the tube delayed today causing me to miss my train? +30m

Is it hot summer week? expect almost everyday to be cancellations of 1h+++

Someone trespassing/ hit by train, cancellations of 1h+++

Signalling problem, cancellation of 1h+++

Fire next to track cancellation of 3h+++

plus more Many days I have spent more than 4hrs just to get home.

Now this 2h 40m commute easily averages out to 4h
