Putting up barriers would be a huge undertaking for the MBTA as it requires the trains to stop in the exact same spot every time they pull up to the platform. This would require replacing the existing signaling system and train cars. Much of the T uses an outdated analog signaling system, which is only now being replaced with a digital system. Likewise much of the T's rolling stock is decades old and won't be fully replaced for another decade or two.

You can make the doors on the barriers wider than the doors on the train to give you some leeway. There are also vertical barrier doors that don't care about door positions.

Well, technically they are fully replacing the rolling stock and signals on the orange and red as we type. Unfortunately it's all gone to shit and years behind.
