You know the feeling: You get to Penn Station and see that the departure board is peppered with trains on STAND BY.

If it was one or two trains...you might just hope it's an isolated incident.

When over 1/3 of the trains are showing STAND BY...we all know this could be bad.

So our bots scan the departureboard, and when 30% of the next trains are troublesome, we notify you according to your preference.
