In 2008, MBTA workers survey the scene of a fatal Green Line collision. An automated system to track and control trolleys is estimated to cost $345 million to $721 million.

I AM amazed, but not surprised, that the MBTA would like to spend more resources than it has on a Green Line safety system that would perhaps stop some collisions (“Cost high for a Green Line anticrash system,” Page A1, Dec. 24). After a disaster, everyone wants to be seen as doing something to avoid another similar disaster.

But this “solution” would take approximately nine years and cost around three-quarters of a billion dollars. Remember the Big Dig? It was supposed to cost an eye-popping $2.6 billion, but ended up costing more than five times that much. This proposed new system would also slow down Green Line trains, which you might think is impossible if you have ever ridden the B line.
