Planning to travel from Ghatkopar to CSMT? Here's what you need to know. The journey covers 39.8 km and takes approximately 75 min – that's including a quick train change at the interchange station. You'll start your journey on the Blue Line and switch to the Aqua Line midway. Don't worry about getting lost – the interchange is well-marked with color-coded signs pointing you to the right platform.

Fare & Tickets: A single journey costs ₹70. Pro tip: if you travel this route regularly, get yourself a Mumbai Metro smart card. You'll save 5% on every trip (fare drops to ₹67), plus you skip the token counter queue. Return journey? That's ₹126 – decent savings if you're doing a round trip.

When to Travel: Trains start rolling at 5:30 AM and the last one leaves around 10:45 PM. During rush hours (8-10 AM going towards offices, 6-8 PM coming back), trains arrive every 4-6 minutes. Off-peak? Every 8-10 minutes. My honest advice – if you can, travel between 11 AM and 4 PM or after 9 PM. You'll actually get a seat, and the journey feels almost relaxing.

About the Interchange: The station change is easier than it sounds. When your train arrives at the interchange station, just follow the signs for Aqua Line. The platforms are connected, and the whole switch takes 3-5 minutes max. Most Mumbaikars do this daily without a second thought.
