ankitaanand28/DA323_IndianRailwayTrainDelayDatasets ? reverse-engineered prompt

Build me a clean mini project for Indian Railway train delays using the data in this repo.

I want a notebook that reads the train list and the per train route CSV files, cleans things up if needed, and shows useful visualizations about delays and cancellations for express trains from Guwahati to Delhi, Mumbai, Chennai, and Kolkata. Please make the charts easy to understand, with clear titles and labels, and include a few interactive plots if possible so I can explore delays by station and train.

Also make sure the notebook is easy to run from the Dataset folder, and add any missing steps so someone else can reproduce the analysis without guessing. If you need to check current notebook or plotting docs online, feel free to do that. Keep it simple and polished, since this is for a semester project and I want it to look presentable.
