The Pennsylvania Railroad's class E2, E3, E7 steam locomotives were of the 4-4-2 "Atlantic" passenger type, frequently called “light Atlantics” after the introduction of the heavier E6 Atlantics. All were similar in size and boiler capacity but differed in firebox type, valves and valve gear, and cylinder diameter. Classes E2 and E3 were built simultaneously. Starting in 1916 a rebuilding program converted ninety class E2a,b,c to class E7s by replacing slide valves with piston valves and increasing cylinder diameter from 20.5 to 22.5 inches (520 to 570 mm). Fourteen class E2 were similarly converted to class E7sa. Ninety class E2a,d, E3a,d were converted to class E3sd. These improvements allowed many of the engines to remain in active service into the 1930s.
The sub-classes differed as follows:
In the first decade of the twentieth century classes E2 and E3 handled all of the fast passenger trains of the Pennsylvania Railroad. As train weights increased due to the switch to steel passenger cars and more cars per train, the “light” Atlantics were usually double-headed. Eventually, as Pacific class K2 and K3 became available, they were relegated to secondary service
For love, I bought diamond rings
For love, I gave my everything
For love, travelled across the land
Through the hail and the snow and the drivin' rain
For love, what did I get?
One love I wish I could forget
Oh Lord, now, what it's doin' to me
No more
I think it's drivin' me crazy
When nothin' can save me
I never thought I'd find me another love
Then I opened my eyes and there she was
I got another life today
I got another life today
A new chance for the new romance
New eyes, new nose
And everything smellin' like roses
I got another life today
I got another life today
You're everything I needed
Yeah, you shook my world
You're just what I been lookin' for
Yeah, you're just what I been lookin' for
Yeah, you're just what I been lookin' for
Too long, I lost everything I had
All my life I was longin', I was feeling sad
Didn't know what I was goin' to do
Lo and behold that's when, a, I met you
We turned it all around from a grey to blue
And I'm feeling more like me and all because of you
Oh Lord, now what ya doin' to me?
Give me more
I think you're drivin' me crazy
When nothin' can save me
I never thought I'd find me another love
And then I opened my eyes and there she was
I got another life today
I got another life today
A new chance for the new romance
New eyes, new nose
And everything smellin' like roses
I got another life today
I got another life today
You're everything I needed
Yeah, you shook my world
You're just what I been lookin' for
Yeah, you're just what I been lookin' for
Yeah, you're just what I been lookin' for
And I loved and a-lovin' till I loved too much
And I gave it everything until my love lost its touch
Till there was nothin' left worth savin'
Oh, and I know that everything I need to make me feel complete
Can't you make a believer of me?
I guess I'm fallin'. Now what I'm tryin' to say
I got another life today
I got another life today
A new chance for the new romance
New eyes, new nose
And everything smellin' like roses
I got another life today
I got another life today
You're everything I needed

You're just what I been lookin' for
Yeah, you're just what I been lookin' for
Yeah, you're just what I been lookin' for, yeah

And everything that I need
Now if you're hungry for love I got all you can eat
