Option 3: Train KL to JB Sentral + Walk to Singapore
KTM Komuter from KL Sentral to JB Sentral (~5–6 hours with connections, ~RM 30–50), then walk across the Causeway to Woodlands Checkpoint Singapore (~15 minutes on foot or shuttle bus). From Woodlands, MRT to the city center (~30 minutes). A more scenic and independent option — good for those who enjoy piecing together a journey. Not faster than the bus overall but more flexible on timing.
