The main touristic use of the train seems to be access to the Taman Negara national park, so instead of sitting through all 10 hours of the trip, it would make a lot of sense to break your trip there.
Heck, in that case, just rent a car in KL and drive to the boat put-in for Taman Negara (which is what we did) then boat into the park. It's only about a 3 hour drive from KL. You can park at that site for a low price. It's certainly true that drivers in Malaysia have a very creative approach to traffic rules, but it is doable. However, we went out of our way NOT to rent a Malaysian vehicle -- we had to go to Avis's top class and the car we got was a Toyota Corolla!
