The bottom two photos are not Harold interlocking itself BUT they will feed LIRR trains between Harold Interlocking & the ESA terminal deep underneath GCT. The photos are also not current, not even for Jan 2014 date of the report the page was snipped from.
In addition, the bottom tunnel in the bottom right photo does not pass through HI but connects to Sunnyside Yards itself. The new ESA terminal does NOT have a train storage area deep underground and will use Sunnyside Yards as the mid-day storage area for the evening rush hour trains. So the stored trains will have to be brought in to the ESA terminal via one of the two tubes under the Hudson/Roosevelt Island, while the evening rush trains are being flushed out via the other tube.
The current Penn Station has an almost 30-year old improvement to the ESA evening procedure, namely the LIRR's West Side Storage Yard. The WSSY was built west of the Penn Station bathtub, the now-mostly overbuilt excavation blasted into Manhattan bedrock by the Pennsylvania RR in the 190Xs. The WSSY is being overbuilt now by Realted/Tutor-Perini in the Hudson Yards development. The last remaining open-to-the sky section of the original Penn Station bathtub is being overbuilt by Brookfield in the Manhattan West development.
