2009年11月，廣安門站被拆除，中國鐵道博物館的**們在搶救文物時，發(fā)現了一批珍貴的近代鋼軌，這些鋼軌絕大部分是外國制造的，標注的生產年代大部分是20世紀初，其中一根所鑄銘文為“造廠鐵陽漢1902”（1902年漢陽鐵廠造）的鋼軌引起了**們的極大興趣。漢陽鐵廠是中國近代創(chuàng)辦的***個鐵廠，也是當時亞洲**大的鋼鐵企業(yè)，而“1902”表明這根鋼軌是中國現存**早的國產鋼軌。**們如獲至寶，把它完整地珍藏在中國鐵道博物館中。京漢鐵路原稱盧漢鐵路（盧溝橋至漢口），修建時將起點從盧溝橋改至北京正陽門西站，因此鐵路開通時改名為京漢鐵路。京漢鐵路的修建有一個**關鍵的人物，這個人就是清末洋務派**之一的張之洞。1889年，清**委任張之洞為湖廣總督，在考察了當地的情況后，他上書清**提議修建盧漢鐵路，得到清**批準。</p><p>

漢陽鐵廠的目的本就是為盧漢鐵路提供鋼軌，修建盧漢鐵路是一波三折，漢陽鐵廠的開辦更是困難重重。1890年5月，張之洞在武昌成立湖北鐵政局，經過親自勘察、反復研究和慎重考慮，張之洞決定將廠址建在漢陽大別山下。1891年9月，漢陽鐵廠破土動工，張之洞對建廠事務“躬親細務，錙銖必較，急如星火，日夜操勞”?？朔酥刂乩щy后，漢陽鐵廠于1893年年底完工，包括煉鐵廠、熟鐵廠、鋼軌廠、鋼材廠等10個分廠，蔚為壯觀，于1894年2月正式點火。但是，鐵廠剛開始投產就面臨一個**大的實際問題——資金不足。清**所撥費用已全部用完，而投產所需資金至少100萬兩白銀。張之洞奏請朝廷，提出設備“分量、分撥”投產，以解決資金周轉問題，減少開工費。他還建議朝廷將建造湖北***炮廠等工廠的資金“撥借”過來。緊接著，有一個大難題接踵而來，由于缺乏經驗，前期技術準備不充分，所用的原材料大冶鐵礦砂和煉鋼爐不匹配，無法提取大冶鐵礦砂中所含高濃度的磷，造成試軋出的鋼軌質脆易裂，不能普遍使用，鐵廠經營陷入了困境。1896年，漢陽鐵廠改為官督商辦，張之洞舉薦盛宣懷接手，之后又對冶煉設備進行了重整改造，鋼鐵質量轉佳，經營銷售一度頗有生機?？酥莸闹剀墢S
