As a tangent, London is adding overground trains as part of its expansion. The Overground is pretty recent (and it shows) as is the fully-automated DLR, and now there's a Crossrail making an appearance. NY hasn't invested in a hell of a lot in overground infrastructure and it feels like that's a logical step in the outer boroughs.
- lhopki01 9y agoCrossrail is underground through London. The Overground uses existing rail infrastructure just under direct TFL management so isn't really new. There are a few new sections but they exist only to join up two lines. DLR is possibly the only real example of new overground trains and partly that is because it follows existing rail lines for quite a distance.
