How does a DC controller work?

Hi, I'm new to model trains. I've recently aquired a DC locomotive and some tracks but I´m missing a way to control it.

I want to spend as little as possible because eventually I will make the jump to DCC, so this is only temporal equipment, so I am considering buiding the transformer/controller myself. I have plenty of experience in electronics and electricity.

What I want to know is how does a DC train controller work:

Is it just a variable voltage power source from -12 to +12, or is it something like PWM?

Prototype Oil Loading Platform

I am installing the Walther's Oil Loading Platform, and would like to know what type of ground/soil/gravel do most prototypical operations use?  I'm inclined to guess it would be gravel so that spilled oil/fluids can be drained away and not be pooled up on the ground.

Does anyone have pictures of actual oil facilities?

Thanks......Grampy

Ernie Hoffnagle wasn't sure if it was a rock or a maybe a dinosaur bone in his garden. He called in some experts and now it's all a big mystery.

Future of the railroad business

I'd like  to hear people's thoughts on the future of the railroad companies, as businesses. Does the future look like a long, slow decline or ever greater profitability? I'm interested in the business, rather that the future of the industry as an employer. 

If you owned stock in a railroad business, do you think it's a good investment for the next ten years? Or is it likely to lag?

Question about oil storage tanks

Todays storage tanks have a berm built around them, was that a standard practice in the early 70s?

The Wathers kit has the berm included, but I dont know if thats correct for 1972.

A Solo Ops Session

If not having regular ops sessions is one of the lemons of life lately, then being able to operate your own layout is definitely the lemonade. After all the setup required for one of my typical sessions, it's all over in a bit over 3 hours during one evening. Reminds me of a holiday dinner: the eating only takes a small fraction of the prep and cooking.

Reattaching Peco (N Scale) closure rail?

When testing out some trackwork today, I discovered one of my PECO turnouts is broken.  Specifically, one of the closure rails has detached from the throw bar.

Please excuse the fuzziness of the pictures, but you can see the floppy rail.

Close Coupling for Passenger Cars

All,  what is the "state or the art" with close coupling of passenger cars today?  Roco and other European manufacturers have been doing it for many years but I am looking at using kits and modifying cars designed for body mounted knuckle couplers,  My prototype has full diaphragms and I use 30" radius curves.

Quick update and a thank you!

Just A quick update. I had an idea that I wanted to see on the layout, if you been following I am building a larger layout and always am looking for some help on projects. This one fell into a project that my friend Mike Whiteman.
