Yes, you are correct. It can be inconvenient to have to step out of the cabin to check the availability of the toilet. Having toilet vacant indicators inside the cabin would indeed be a helpful feature, as it is in the ICF coaches of the Coromandal and HWH MAS Mail trains. It would be good if the LHB coaches of the MGR Chennai Central - Santragachi AC SF Express also have this facility for the convenience of the passengers.

That's great to hear! It's always comforting to know that the blankets, towels, and bedsheets provided on trains are clean and fresh. The fact that they are brand new and properly washed shows that the authorities are taking hygiene seriously. The sealed plastic cover is also an assurance that the bedsheet has not been used before. It's these small details that make the journey more pleasant for passengers. Thank you for sharing this information!
