This Essentials included ehbk2006's High Definition cantanery model and some custom supports props, necessary for Rail_Catenary_Mod_V3 and HSR_Catenary_Mod, and future ELR Catenary Mod       Install: 1. Be sure delete the old version and "NL-Special-Cantanery-props.dat" if installed    2. I recommend Extract the "Catenary_Essentials.dat" in zip file into my Catenary_Mod main directory (SimCity 4\Plugins\Network Addon Mod\z_Catenary_Mod)              Uninstall:    just delete the Catenary_Essentials.dat file.      Dependencies:    None   Any question or suggestion, please post on the topic in SC4D forum: https://www.sc4devotion.com/forums/index.php?topic=6316.0                          Credits & Special Thanks:     ehbk2006, for HD-Catenary-model                plunderer,  2009-06-24
