The Railwaymen's Union of Malaya (RUM) has threatened to protest in Transport Ministry Liow Tiong Lai's constituency if he refuses to engage them on the railway network access agreement.

"I have been trying to meet Liow and Liow had promised to meet but to date, the meeting did not happen.

"We are angry and we may picket in Bentong so that he realises that RUM is serious as it is a matter of workers' rice bowl," said RUM president Abdul Razak Md Hassan.
