I took a Vistadome Trip in Deccan Queen at the end of August.
Rode on my Activa to Mumbai at the start of September.
And took a bus trip just last week in Shivneri.
I have somewhat regular work in Mumbai.
Although...
more... it totally depends upon person to person, reaching station is a tedious process for most people in Pune. Especially when you have to reach for Specific timings of trains rather than going to a bus station and simply catching a bus whenever you like.
Unless and until I'm specifically going to South Mumbai (Bombay High Court), I'm not looking at trains. Especially nowadays when most people aren't freely allowed on Mumbai Locals
