It details various criteria for each system, including ID, voltage, and frequency. The document also outlines the grid connection of substations and the main energy supply sources, differentiating between public/railway grids and public grids with local RES, as well as energy tariffs such as grid tariffs and on-site PPAs. Furthermore, it provides a comprehensive table of component specifications, listing values and references for OHL frequency, voltage limits, current limits, and efficiencies of various components like OHL, direct transformers, and converters. A section on parameter definitions includes operating life for vehicles and infrastructure, nominal and effective interest rates, and annual inflation in Germany. The document's core purpose is to offer a detailed technical and economic comparison to inform decisions regarding railway electrification strategies.",{"@graph":68,"@context":122},[69,83,105],{"@type":70,"itemListElement":71},"BreadcrumbList",[72,76,78,81],{"item":73,"name":74,"@type":75,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":77,"name":9,"@type":75,"position":14},"https://docshare.wps.com/document/",{"item":79,"name":40,"@type":75,"position":80},"https://docshare.wps.com/document/research-report/",3,{"item":82,"name":64,"@type":75,"position":19},"https://docshare.wps.com/document/sustainability-13-08234-v4/182866/",{"url":82,"name":64,"@type":84,"image":85,"author":90,"headline":64,"publisher":93,"fileFormat":96,"inLanguage":63,"description":66,"dateModified":97,"datePublished":98,"encodingFormat":96,"isAccessibleForFree":99,"interactionStatistic":100},"DigitalDocument",{"url":86,"@type":87,"width":88,"height":89},"https://docshare.wps.com/thumbnails/sustainability-13-08234-v4/182866.png","ImageObject",300,407,{"name":91,"@type":92},"Cart","Person",{"url":73,"name":94,"@type":95},"DocShare","Organization","application/pdf","2026-10-31","2026-09-02",true,{"@type":101,"interactionType":102,"userInteractionCount":104},"InteractionCounter",{"@type":103},"ViewAction",12,{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the main differences between OHLE and OHLI systems?","Question",{"text":112,"@type":113},"The OHLE system is an extension of an existing electrified section, while the OHLI system creates an isolated electrified section.
