CSX traffic under Philadelphia Art Museum??

Just wondering, how many CSX trains pass under the Philadelphia Art Museum on the Philadelphia Subdivision?? I know a lot of Norfolk Southern, CSX, and Canadian Pacific trains use the High Line past 30th Street Station, especially double stack trains. So if CSX uses the High Line for trains, how often is the line under the Philadelphia Art Museum used?

It’s used quite a bit actually. The preferred route for trains through Philly is along the river to RG tower for ease of changing crews (nothing currently goes through Philly without a crew change). If trains are routed via the High Line, the crew change takes place at 58th street, a van ride is required to get the crews to and from the on duty point at RG. Trains originating in South Philly Greenwich yard have to have crews taxied from RG. So currently 702-703, 140-141, 032, 034- 031/033, 410- 409, 438- 439 mostly are routed through that tunnel, as well as one local, I believe, not sure of the symbol.
