THIRUVANANTHAPURAM: Former Finance Thomas Isaac has responded to 'Metroman' E Sreedharan's objection to the K-Rail project. 'E Sreedharan was highly respected by the people of Kerala. However, something went wrong ever since he joined the BJP. Kerala was not on the railway map of India during the Congress rule as well as the BJP rule. The railways have no compulsion that trains should operate in the state. E Sreedharan is well aware of that,' Thomas Isaac wrote on his Facebook page.
