Malaysia Jungle Railway — practical things worth knowing before you go

Pulled these out separately from my trip report since they are easy to miss. Cash: Get a decent amount from KL before you head out. ATMs become genuinely scarce once you leave the main cities. We were advised to bring around 800 ringgit per person for incidentals and most people used close to that. The tip kitty was 100 ringgit and was fully used by the end. Torch: Bring a small handheld one. The nighttime safari needs it and some of the city evening walks are on unlit or uneven paths. Clothing: Cover knees, midriffs and shoulders throughout. Both for religious respect and because mosquitoes are active. Do not rely on repellent alone. Trains: Heavily air conditioned. Bring something warm to pull on even if it feels counterintuitive when you are sweating outside. Valuables: Most accommodation does not have room safes. Keep anything important on you or leave it at home. Swimwear: Bring it. The Perhentian Islands section involves boat trips and snorkelling. Food allergies: Not a good trip if you have significant dietary requirements. The vegetarian on our trip had a hard time despite the guide helping with ordering. Worth having a direct conversation with Intrepid before booking if this applies to you. Plugs: UK plugs work throughout Malaysia but bring an adapter if you are coming from elsewhere. The trains have underseat charging points which are useful on longer legs. eSIM: We all used them. The person with the best connectivity across all locations was using Hola Fly specifically — worth knowing if you are comparing options.
