Thank you, Mr. Chairman, and honourable members.
I will start with an introduction about us. I am Jamal Hematian, the VP of product engineering, and I have Max Vanderby with me. He's our director of production engineering. We run the engineering department of National Steel Car.
National Steel Car is the only railcar manufacturer in Canada. We are over 100 years old. We serve North America and some international markets. Our workforce is about 2,000 people and sometimes goes up to 2,400 people. We design and build freight cars: 12 different cars and 76 models. We have five flexible lines, and our maximum production capacity can go between 12,000 to 15,000 per year.
We are certified to AAR requirements and we are the only railcar manufacturer in North America certified for ISO. We have over 300 patents on different car designs and we spend about $5 million to $6 million on R and D projects every year.
In this slide you can see the variety of railcars we design and build, including tankers. This next slide is important because it shows our AAR certification. You can see in the table that it covers almost every type of railcar, including tankers. We are certified to design and build different tankers, repair them, or refurbish them.
The point about tankers is the rules and the governing bodies. It's very heavily regulated, and there are different organizations that have rules, and we have to obey them and to follow them. If you compare a tanker to another freight car, we don't have that much option of making decisions because everything is in the book and you go by the book.
I summarize major organizations and rules in this slide. There is an Association of American Railroads, which is AAR, and there are different manuals that I summarize over there. There are two important ones, if you take note of them. The third line is CPC-1232, Petition-1577. Also there are more rules from CFR and PHMSA that we have to obey and follow.
On top of that, there are Transport Canada, FRA, ASTM, AWS, and API. You can see that for tankers, it's very well organized and governed, and everybody has to play by the same rules. On top of that, it's well documented. NSC has a certification to design and build tankers. For every order, we have to make a package of drawings and we have to send it to EEC, which is an engineering equipment committee at AAR. They will review it and they give us a certificate for that order with that package. Even during the process if we want to change anything in there, we have to go back through the process and tell them what we want to change. They review it and they get back to us with yes or no. It's a very heavily regulated environment.
There are so many different types of tankers. In total, I think there are over 334,000 tankers in service, but that includes all different types of tankers. They categorize them based on the application of those tankers, on what service they do. They classify them as pressure, non-pressure, jacketed, non-jacketed, insulated, and non-insulated.
When we talk about DOT-111, we are talking about non-pressure tankers. Within this group, we again have subsections. We call them packing groups I, II, and III. What this means is that for the commodities you are moving with these tankers, what's the level of the potential for risk or danger with them? Group I is the highest. It is the most critical one. Group II is a little bit lower, and group III is much lower.
This next slide shows the DOT-111A100W1, which is general purpose, non-pressure, and good for groups I, II, and III. It addresses all of them. Crude oil and ethanol fall into the group I and II packing groups. The first one, at 31,800 gallons, is non-jacketed. The second and third ones are insulated and jacketed. There is another point to that, and we have to be careful. There are two things that we have to consider. We have jacketed with insulation, and we have thermal-protection jacketed. So on the insulation and the thermal protection, they are two different things, and you have to deal with them differently. The design is not so different, but they are two different animals, so we have to be careful with that.
At NSC, we design and build the first two right now. We have the approval to go ahead. We have shipped the first one—I think 25 or 30 tankers right now—and we are building both of them at the same time.
The next point I want to mention is very important. Again, we have all of these discussions about improvements and changes in design. For all of these tankers within DOT-111—I am focusing on this one and not going to any other tanks, because it's going to be endless—for crude oil and ethanol, we have two generations before 2011. They are called legacy cars. The code is HM-251. For this meeting, let's call them old cars.
In 2011, a new package came in to improve the design and make some changes, with about 80% of these changes being about the safety of these tankers, and they called that car CPC-1232. If you remember, when I was going through the rules I said to remember that CPC-1232 is the key. There were changes from legacy cars to these, which they called “good-faith cars”. They called the CPC-1232 the good-faith car. So if you hear that, you can differentiate between them.
One major difference between legacy cars and good-faith cars is the gross rail load. When we talk about gross rail load, it means the car body, the truck or bogies and suspension, what you put inside, and how much it weighs all together. The legacy car was 263,000 pounds; we call it gross rail load.
That's fixed in those cars, just split it into two portions, car body and what you put there. What's the car body? We call it light weight. What you put there, we call lading or capacity. If you increase the light weight, you lose your capacity because the sum is fixed at 263,000. If you reduce light weight, you increase the capacity.
So, the legacy car is 263,000 pounds GRL and the new, good-faith car is 286,000. The gross rail load jumped from 263,000 to 286,000. Because of this jump, to increase the efficiency of the system, they had to review the design and determine what needed to be done to improve the car. At the same time, they looked at other incidents that happened with tank cars and put it all into one package. In a circular letter from the AAR regarding the CPC-1232, they said that going forward, we had to follow this. Nobody could design or build the old one.
