軌道養護對於軌道的安全性與使用年限有著舉足輕重的角色，然而臺鐵目前的養護作業仍有部分採取人工紀錄與管理，如此不僅養護效率不佳，也不便進行後續的追蹤，而以紙本呈現養護紀錄亦無法直觀對應現場待養護之位置。
本研究嘗試建立軌道資訊模型並應用於臺鐵工務養護之中，首先取得臺鐵新左營車站區之軌道圖檔作為建模參考，而由於軌道物件同質性高，採用Autodesk Revit 軟體搭配Dynamo 以自動化的方式建置軌道模型。接著探討模型中各項軌道物件之分段與編碼方式，並新增物件參數與給予物件資訊。最後初步建立一套運用軌道BIM 之軌道養護流程，利用建置完成的軌道資訊模型串接養護管理資訊系統以取得待養護資訊，並於養護作業完成後更新改善資訊，完成一系列軌道養護流程。
研究結果顯示可順利將養護管理資訊系統取得之養護資料匯入軌道模型中建立養護標註並呈現待養護資訊，於養護作業完成後將養護改善資訊存入軌道物件之養護履歷中，並同步匯出供養護管理資訊系統更新，初步驗證運用BIM 技術於軌道養護流程之可行性。

Maintenance plays a significant role in the safety and service life of the railway. However, some of the current maintenance operations of Taiwan Railway still adopt manual records and management. It is not only inefficient but also inconvenient for further tracking. Presenting the maintenance records on paper also cannot directly correspond to the on-site location.
In this research, we attempt to establish a railway information model and apply it to the maintenance of Taiwan Railway. First, the railway drawing file of the Taiwan Railway Xinzuoying station acquires as a reference. Due to the high homogeneity of railway components, we use Autodesk Revit with Dynamo to build the railway model automatically. Then discuss the segmentation and numbering methods of various railway components, adding component parameters and give information. Finally, we preliminarily established a railway maintenance procedure using BIM. A completed railway information model is used to connect the maintenance management information system to obtain maintenance information. After the maintenance work is over, the improved data would be updated to complete a series of track maintenance procedures.
The result shows that the data obtained from the maintenance management information system can import to the railway model to create maintenance labels and display the information. After the maintenance work is over, the improvement data is stored in the maintenance history of the railway components and exported simultaneously to maintenance management information system. Preliminary verify the feasibility of using BIM technology in the railway maintenance process.
