Train 304 from Lop Buri to Bangkok (Hua Lamphong) is a commuter train service with 3rd class seats. This train stops at more stations than the express services.

Train 304 departs from the old Lop Buri station in the city centre. I took this trip in December 2025, a few days after Lop Buri 2 Station had opened. The new Lop Buri station is about 9 km from the city centre, and it serves the express trains on the Northern Line. If you want to get a faster train to Bangkok, there is a shuttle service at Lop Buri that will take you to the new station.

Lop Buri Station now only serves Commuter and Ordinary class trains, which was ok with me.

Tickets for these trains are bought on the day of travel at the station, and they are much cheaper than the express trains. The ticket from Lop Buri to Bangkok cost 28 THB (0.88 USD). The ticket shows Lop Buri 1 as the station, though Lop Buri is also used.

Train 304 departs Lop Buri at 8:00 am and arrives at Bangkok Hua Lamphong at 10:30 am. The total distance is about 146 km.

The seats are non-reclinable bench seats.

There are also straps for standing passengers, which are required on some services during peak hours.

It wasn’t until later on in the trip when I checked out the other carriages that I noticed that some seats were padded.

There are no food and drink services onboard, but food venders get on and off during the trip.

The train also has a western-style toilet onboard.

The train began is service for the day in Lopburi so there was no delay in departure. South of Lopburi you can see where the line splits for the bypass to Lop Buri 2 Station.

The train travels through the broad plains of Central Thailand, and the occasional mountain among the green rice fields in December makes for beautiful scenery. I also appreciate that the windows open on these trains, and most people prefer the windows open (when it is not raining).

The train stops at many small station along the way that the express trains to and from Chiang Mai pass through.

One of the main stops on this route is Ayutthaya. This was the only station where you will see western tourists, and you should visit if you have never been.

Between Ayutthaya and Bangkok you can see the construction of the Bangkok – Nong Khai high-speed railway.

Outside of Bangkok, the train stops at Rangsit Station. This the current northern terminus of the SRT Dark Red Line.

Train 308 follows the same path of the SRT Dark Red Line, but it goes to Bang Sue Junction instead of Krung Thep Apiwat Central Terminal (the central station of Bangkok). Train 308 then continues from Bang Sue Junction towards Hua Lamphong.

Our train stopped short of the station while waiting for another train, and in the end it was delayed by about 10 minutes.

Even though the commuter train is slower, I like that it departs from Lop Buri Station and that it arrives at the classic Hua Lamphong Station.
