As I understand the situation from someone who had been involved in the project since the very early days but retired a couple of years ago, the idea behind the paint scheme of the cars was that they were purposely kept neutral so that they could have a final paint scheme applied via vehicle wraps shortly before the revenue service launch.Not sure where you heard this, but you generally know everything drum. I read (from Metrolinx, early in the process of building Line 5) that the grey was chosen to match higher-order transit, specifically the Line 1 Toronto Rockets. This doesn't really hold the test of time (like everything Metrolinx does) because the Line 3 trains and the new Line 2 trains will all sport color to some degree, albeit not as much as the CLRV or SRT cars.
And while that may have been the plan 15 or 20 years ago, the amount of turnover in the various organizations involved in the project likely means that the plan from that long ago has simply been forgotten.
The TTC stopped painting subway cars simply because it no longer had to.I would have assumed the TTC stopped painting subway cars simply because it's been cash starved for decades and could save a few bucks; not for any aesthetic reason.
The first several batches of subway cars were painted red because they were steel, and steel needs to be painted in order to keep rust at bay. Within those batches they received one batch of otherwise identical cars that were built of aluminum, and were kept unpainted because aluminum doesn't rust but instead forms an oxide layer that is virtually impervious to oxygen - and so doesn't deteriorate like steel will.
Since then, and until the Toronto Rocket cars, all cars were built with aluminum bodies. They still used steel underframes, which had to be painted and treated in order to stop rust.
Then the Toronto Rocket cars arrived, and are made of stainless steel. Much like aluminum, the type of stainless used doesn't rust through the creation of a passive oxide layer.
So why bother spending the money on paint when you don't need to?
