Implementing digital signalling on the core commuter lines into Manhattan would alleviate this issue and deliver a broad array of benefits across the wider region. One of the options being explored by Network Rail to enable more trains to run into London Waterloo is using European Train Control System to enable up to 44 trains per hour per track. Of course that would require far more efficient train turnaround, wider platforms and possibly through-running at Penn. Still thought it would be far cheaper than new lines.

and two more lines to come under the hudson via the gateway rebuild. that likely needs to happen before any serious thru running push.
other than ptc and ctc signaling upgrades i dk about commuter rail, nothing else i don't think, but at least cbtc automation is being overlayed on the traditional block system and is moving along in being implemented for the whole subway system. although found to be hard on the brakes, the canarsie L train and flushing 7 train pilots were otherwise successful and its been expanding. so not bad for by far the most complicated, interlined subway system.
also interesting that mta had been piloting subway automation off and on since the 1950s, although it seems they took a break from that from the mid-1960s until now. unions, ha.
and since you mention other cities, in the usa i think the path train has cbtc now too, and i know sf bart and at least one line in philly use automated signaling. probably others also do these days.
