Many many years ago I took the train from KL to Singapore. The most dangerous aspect was the ice-cold air conditioning - I thought I was going to get hypothermia!
But that was 20 years ago (OMG!) before the persistent troubles in southern Thailand. I mean far south Thailand (many refer to Phuket as southern Thailand, but it's the provinces further south, bordering Malaysia).
There's a separatist 'war' going on and there are daily reports of bombings, shootings and indiscriminate attacks. targets include: tourist hotels and bars, banks, cinemas and entertainment venues, shops, markets, supermarkets, schools, places of worship, petrol stations, transport infrastructure including Hat Yai international airport, railways and trains. Consequently there are DO NOT TRAVEL warnings in place. Travelling through the provinces of Yala, Pattani, Narathiwat and Songkhla is very risky - a high chance you'll be in the wrong place at the wrong time. And because of the government warnings, it is extremely unlikely your travel insurance will cover you for medical costs or will be able to arrange evacuation if you are injured in one of these attacks.
My advice is to catch a plane, and hop-over this part.
As for the rest of the journey - it's a great adventure undertaken by many thousands of travellers each year. It has inherent risks and dangers - but not anything that should put you off. Just exercise common sense and due care.

I am a Singaporean working in Songkhla. There had not been any terrorist attacks, bombings, whatever during my. 2-year stay in Songkhla. The bombings in Hatyai were in 2005. Since my move here, I had not received any government-issued travel warnings.
If you take the northbound train from S'pore, you will need to change trains in KL. Aim for night train as it's a very pleasant ride. So far i've done up to Bangkok, you may wish to check on the Thai Rail website for details. almost 8 years ago
