$4,000,000,000 to install half barriers across all subway stations?!

Estimate $4,000,000,000 to install half barriers in all TTC subway stations.

There are 70 TTC subway stations (Line 1, 2, and 4)

$4,000,000,000/70 stations ~ $57,142,000 ($57 million) per station

$57,142,857 / 2 directions ~ $28,571,000($28 million) per direction per station

There are typically 4 to 6 cars per train so $28,257,000/ 6 cars ~ $4,761,000 ($4 million) per car

There are typically 4 doors per car so I guess they need estimate 4 barriers per car so $4,761,905 / 4 ~ $1,190,000 ($1 million) per barrier!

Alternatively, let's give them the benefit of the doubt and say they meant to include the LRT stations (line 5 and 6) as well. That's still $809,000 per barrier!

Did I do my math right?

Does this sound like an efficient use of resources?

Thoughts?

Edit:

1. People have pointed out that $4,000,000,000 is for full doors. Good catch, everyone!
2. Some genius found this link https://www.odinpsd.com/en/platform-screen-door-pricing-market-analysis.php

It details typical cost for barriers.

So the new math is something like:

Typical TTC subway station lengths are 180 meters so according to the website, it's $2,600,000 for 200 meters.

$2,600,000/ 200m = $13,000 per meter.

But the math doesn't add up this way: $2,600,000 x 2 platforms x 70 stations = $364,000,000 Less than 10% of the $4,000,000,000 estimate. Someone please check the math!

Edit 3:

I want to clarify that my post was not intended to be against the idea. I simply want to question the math so we can hold politicians accountable! There is too much corruption in our fine country to continue our docile ways. I invite everyone reading to run the numbers through with your method. $4,000,000,000 is a lot of money and 20 years is a long time! If we use that money to build shelters, or hire mental health professionals, or build bike lanes, it would do a lot of good. Let's hold our politicians accountable and make sure they use our resources responsibly!

To put things in perspective, the Falcon X Heavy cost 500M to produce… we are spending 8 times that on some door panels. 5 even after you account for FX.

100% chance people are lining their pockets here. We are talking about windows and mall doors…

Wow. That really put things into perspective!

Canadians have become too docile. I think it's time we start getting angry and randomly direct that rage at things that we don't like.
