MRT having more spaces for passengers

Recently I realized that more SMRT trains are having cars without seats, i.e. you can only stand in that car. It greatly increases the number of passengers that train can take and smartly, the "standing car" is alternate between normal car. I find it as a very smart and effective measure since when the train is very crowded, one would be more or less forced to stand all the way through in the standing car unless one finds it rational to squeeze through the other standing passengers to another car to test his luck in finding empty seat. This new train set up surely will make the shareholders of SMRT very happy people as it lowers the maintenance cost (i.e. no more seat to repaint and replace) and hence, the profit. It surely will supplement the increase of transport fare due to the oil price increase, which amazingly when the oil price drops, the minister said that the transport fare is NOT linked to oil price. What an amazing counter argument.
