Longer and faster, the underground is the workhorse of the Bangkok Transportation system. It connects business and several residential centers outside of central Bangkok.
Starting at Bang Sue and ending at HualumPhong Train Station (Bangkok's main train station), the MRT intersects with the BTS Sukhumvit line at Mo chit and again at Asok and the BTS Silom line at Sala Daeng.
With a map the BTS and MRT can be worked so that any place within Central Bangkok is easily reached.
Plan your city tour around the BTS/MRT for the most timely results.
Hours of Operation: 6am to midnight

Peak hours: 6am to 9:00 and 4:30pm-7:30pm
Paying for the MRT has a few more convenient options over the BTS. But there is no discounted structure
A single journey is calculated by distance, from 15-40 baht. You can buy at the counter or make change at the and buy a token at the token vending machine.
There are special rates for seniors 60 and older and children under 14. Also calculated by distance, a single journey is just 8-20 baht. Children under 90 cm are free.
For short stays, they are not so smart, just at little faster because you don't have to stop to buy a ticket. The rides are the same price.p
The day pass is much the same, more often the not you won't spend a 100 baht a day on the MRT. However, the 3 Day pass is a bargain but the MRT doesn't go to as many places of interest for tourist as the BTS.
