Engagement Overview
State Railway of Thailand (SRT) operates the nationwide rail network, with locomotive maintenance depots in Bangkok and regional centers. The maintenance fleet requires multiple grades of industrial lubricant year-round, in significant volumes.
Sahawatthanakit (1988) Co., Ltd. has been entrusted as the supplier for:
- Engine oil API SP/SN for diesel locomotive engines
- Hydraulic oil ISO VG 32 / 46 / 68 for maintenance equipment
- Gear oil GL-4 / GL-5 for reduction gears and ground vehicles
- ATF Dexron III for automatic transmissions in service vehicles
Engagement Challenges
1. Batch-to-batch consistency
Heavy daily use means that even small variations in additive package or viscosity drift accumulate into wear-pattern differences over the engine life cycle.
Solution: Every batch ships with Certificate of Analysis (COA) from the manufacturer's lab plus the latest Material Safety Data Sheet (MSDS). SRT's QC team can verify viscosity, flash point, TBN, and sulphated ash on every delivery.
2. 24/7 Logistics
Locomotive depots don't pause for weekends. If oil hits critical level on a Saturday, replacement must arrive in time to keep trains running Monday morning.
Solution: Emergency standby contact + dedicated Bangkok warehouse stock enable <24-hour delivery for urgent orders. Regular deliveries run on a fixed weekly schedule.
3. Compliance documentation
As a state enterprise, SRT requires full documentation per Office of the Prime Minister regulations — tax invoice / delivery note / COA / MSDS / warranty certificate — for every delivery.
Solution: All 5 documents issued per delivery, with soft copies emailed same-day and hard copies following.
