Please note that sv4-tour.zip by Luigi Fenza - presently available at Trainsim.com - may cause compatibility problems or other errors with your copy of Train Simulator.
This activity package contains unauthorized, outdated copies of the KLW Seaview Rollingstock Megapack, Seaview MOW Crane, and early v3.1 Seaview Express stock.
By installing this activity and its content, it is most probable that you will unintentionally override the latest KLW-authorized versions of this equipment. This will downgrade your addons and cause potential errors with Train Simulator.
With this said, we suggest that you do NOT install anything from sv4-tour.zip.
