Many enthusiast types are formed with 鉄 (てつ) as a suffix, e.g., 撮り鉄 (photographer), 乗り鉄 (rider), 音鉄 (sound recorder), 模型鉄 (modeler). These are slangy but very common in fan communities. Use them to sound like an insider.
Do not translate 'railway enthusiast' literally as 鉄道愛好家 (てつどうあいこうか). While understandable, it sounds stiff and formal, and is rarely used in everyday conversation. Stick to 鉄道ファン or the slang terms.
For a train-riding enthusiast, a local train journey is the greatest pleasure.
