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(xiàn)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(biāo)注的生產(chǎn)年代大部分是20世紀(jì)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(dāng)時亞洲**大的鋼鐵企業(yè)，而“1902”表明這根鋼軌是中國現(xiàn)存**早的國產(chǎn)鋼軌。**們?nèi)绔@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，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(guān)鍵的人物，這個人就是清末洋務(wù)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(dāng)?shù)氐那闆r后，他上書清**提議修建盧漢鐵路，得到清**批準(zhǔn)。在修建鐵路所需的鋼鐵材料問題上，張之洞在奏請修建盧漢鐵路的奏折中提出“造路之鐵可用華產(chǎn)”“購買材料取之海外漏危太多，實為非計”。他主張修建鐵路必先自造鋼軌，因此他開始一并籌辦漢陽鐵廠。但*過了一年，因東北局勢緊張，清**將盧漢路款調(diào)撥給東北鐵路，盧漢鐵路暫?；I建，直到1895年甲午***后，清**才決定借債再次修筑盧漢鐵路。</p><p>
