1930s Streamliners by MTH on Kens layout

This week I've finally got my custom made E2 City of San Francisco back up and running, so here it is on the layout.
Outer O72 loop: E2 City of San Francisco set (custom built by me on a MTH Railking E8 chassis) with mixed freight
Inner O72 loop: Railking Pennsy Torpedo with K-Line Fleet of Modernism 15" coach set
