Okay-Todays the question should be an easy one. As part of this new system the F series used this new load bearing principle , it is ?
Bonus question :
EMD Built how many F-7 for the following ?
US Roads _____
Canada ______
Mexico_______
The Bloomberg truck introduced the “outside swing hanger”, increasing the width of the bolster and improving side to side stablity.
Production:
F7A = US 2261, Canada 80, Mexico 25
F7B = US 1420, Canada 47, Mexico 16
FP7 = US 297, Canada 57, Mexico 18
Atlantic Cental , sorry wrong on all accounts. Hint : try not to look at the F unit as a bigger picture item. On the bonus try looking at all F units produced in each country vvs F7A , F7B exclude the FPs,
Easily found on the web. The F was the first to use the entire body as the load bearing structure. What today we would call a “monocoque” design to be fancy.
This makes no sense???
And, if you are refering to the bridge/car body design, E units where built the same way and actually appeared before F units?
Who’s production numbers are you using?

Here is the Wikipedia write up for F7’s with statistics.
http://en.wikipedia.org/wiki/EMD_F7
Here’s the same for FP7’s.
Well, I didn’t get my info from Wikipedia, but it is the same!

Well he did say F’s - so add up FT;s, F2’s, F3’s, etc.

What is the correct answer?
No the second part of the question was “F-7”
As part of WHAT new system?
Geez , sorry guys left early on Friday and this week end I had a major home improvment project going on at home and no time to check in.Also I usually give the answers Monday mornings which allows more time for people to take part in the post. My source for this post is a book called " The great book of trains " by Brian Hollinsworth and Arthur Cook . Not sure of their “system” used. There statement is as follows - "Carbody shell stressed and formed part of load bearing "
The count they used is as follows
US - 3681
Canada - 238
Mexico - 84
If you include FP-7 with train heating boilers you can add another 301 units to the count.I did not include these.
FYI-I very rarely use the web for sources and tend to use articles from manufacures , books or even model railroad magazines. I do not like to use Wikipedia. It is my understanding that any one can add or detract from the information displayed , I do not necassarily trust this source because some one with an agenda or simply wrong information can give out false information. I want the answers to be correct as possible. Thanks for taking part in the post [:)]
Wikpedia is nothing more than an OPEN forum actually. ANYONE can alter the contents of any page so the accuracy of the information becomes questionable.
Further, the guy is right. The E units used the bridge chassis long before the F units were even a gleam in EMD’s eye.
IF you are going to ask these questions I suggest you have YOUR facts and ducks lined up BEFORE posting and have some documentation to support them OTHER than Wikpedia.
Nuff said I think!

So, the end of Friday Night Trivia.
Rich: I write for Wikipedia and am not just anyone. It takes a lot of effort to write something worthwhile that can be used as a source. I hope to see some of the efforts of my fellow Wikipedians locked so that we have a more permanent type of record. As to what you can find in books, magazines or other articles, fine. Some of them repeat the same mistakes from the past and that information gets repeated ad naseum. As for Wikipedia its use will become more common as it gets better. Not everyone has all the time and resources, nor can they afford them. Wikipedia will get you a common answer.
Look for SSW9389 in the rewrites and proofs on Wikipedia. The facts and documentation that go in to my work on Wikipedia hopefully save a lot of other people a ton of work. Get your facts in a row before you trash my work. Better yet write something of your own!

My aren’t we puffed? LOL
FYI, look up the EMD GP-18 and note the user roads. You’ll see my addendum to the Seaboard Air Line Railroad regarding their merger with their arch Rival to form Seaboard Coast Line.
Yes I to contribute to Wik. I contribute in many areas of it and I too get my research and facts straight as do you. NOT everyone bothers my man. Come down a tad…
