The Dadar to Thane route runs along the Western Line - one of Mumbai's lifelines that moves millions of commuters every day. This 20.4 km journey covers 12 stations and takes approximately 30 minutes by slow train. It's a straightforward journey without any line changes required.

This route includes some stations that fast trains skip, so you'll need to take a slow train for part or all of your journey. Slow trains stop at every station but are equally comfortable - they just take a bit longer. The advantage? They're more frequent during off-peak hours, running every 5-8 minutes. Plus, you'll get to see more of Mumbai's suburban landscape along the way!

For the best experience, I'd recommend traveling during off-peak hours if your schedule allows - between 11 AM and 4 PM or after 9 PM. The trains are considerably less crowded, and you might even get a seat! If you're a first-time Mumbai local traveler, start with first class (₹65) to ease into the experience. The coaches have yellow stripes and are noticeably less packed. Once you're comfortable with the system, second class at ₹5 offers the authentic Mumbai local experience.
