I want to see coverage of worldwide development and use of freight car load sensors, and on-train derailment detectors, including the exact details of how these devices work.  I also want to see explanations of how they work with ECP brakes and with conventional pneumatically controlled air brakes. I am particularly interested in the recent plan to equip passenger trains on India Railways with derailment detectors.

In How It's Made/Done" - do a series of in depth rail car mfg. or locomotive mfg, (within what they will actually let you see). Plenty of photos showing the various steps. Something about methods, costs, sourcing of components. Follow the mfg of wheel sets, traction motors, diesel engines, generators, wiring an locomotive, casting couplers, etc, etc.

I was an attendee at Cincinnati Railroad Club's tour of AMTRAK's Indianapolis Repair Facility on Nov.7th. It is the former New York Central's Beech Grove Indiana Locomotive shop where NYC built and overhauled their locomotives. It is huge. The tours 48 members were guided by four Amtrak employee guides who gave us an up close view of the work being done at the shops. They rebuild diesel locomotives and passenger cars. They send the prime movers, motors and generators out for rebuilding by contractors. They install the PTC upgrades for the locomotives. We saw a superliner after it had had the exterior water blasted to remove paint and decals down to bare stainless steel. It got new airconditioner equipment, water heater, rebuilt seats, rebuilt trucks, etc. One of our guides took delight in telling us about the cleaning of the toilet retention tanks. (Somebody has to do it.) We saw both a locomotive and a viewliner in separate paint booths being painted. We also saw the two Breda Talgo train sets in storage. 

I think TRAINS had an article about Beech Grove years ago and think stories about it, Amtraks Wilmington Shop, the major shops of the class I's, the shops of the independent locomotive rebuilders and the car builders are worth consideration.

One thought is an update on "The ABC's of Railroading" articles that appeared in some of the 1967 and '68 issues of Model Railroader. Subjects covered included wheels, grades, air brakes, etc.

I have heard it expressed that people do not like technical coverage.  Their eyes glaze over.  It is disparagingly called "rivet counting."  Instead, what they call for is more coverage of the "human element" with pictures showing people interacting with railroading.  The reaction to this thinking is to make technical coverage palatable by making it simple, light, and brief. 

I think this trend underestimates the readers, thier interest in techincal discussion, and their ability to comprehend it.  So I would like to see technical articles that go deep, but at the same time, offer the reader the luxury of technical writing that is done with the skill of making it understandable and interesting to those not well versed in the art.  

One area that is full of technical details is passenger and freight car trucks, and also diesel locomotive trucks.  I would welcome a technical article exploring the reasoning and design tradeoffs in suspension, ride, and power distribution of trucks.  I have seen good coverage of the variety of locomotive models and their types of trucks, but never much on the intricate principles of those trucks.

If you cannot explain a complex subject simply, you don't understand the subject.

Neil deGrasse Tyson is the perfect example, explaining astrophysics in a manner that can  be comprehended by Joe Sixpack.  He understands his audience and communicates in a manner they can understand.  Too many technical authors believe their articles should be able to explain all the technical questions that would get posed in a Doctoral dissertation defense and leave the audience for the article knowing nothing more about the subject than they did when they started reading it.

I saw enough similarities that I thought maybe I had met you before. Don't take that the wrong way.

I like technical stuff.  I want to know what is inside electric locomotives.  I see cutaways of E units or F units, but other than one GG1 piece, I have litle idea how electrics work inside.  I see box cabs with front and rear "porches" over the wheels.  On some of the porches are two large vertical cylinders, what are those?

A couple years back there was an issue devoted to E-units, and one article was about Blomberg trucks.  I found that fascinating.  Trucks are not just sideframes with axle holes, they are complex levering arrangements.  I'd like to see more on them.

DYnamic brakes are rarely more than this sentence: "Dynamic brakes turn the motors into generators to slow the train."  Fans talk of dynamics "whining", Since the motor/generators turn motion into electric current, I assume fed into resistors, what exactly whines?  Resistors in my world are silent.

MU uses  big multiwire cable, and a few hoses.  What is going through each one?  What has to be connected to what to MU locomotives?

Why does the locomotive paint scheme on Amtrak seem to be unrelated to that of the coaches?  Any designs that never came to be?

How do they "start" locomotives?  I assume they don't just turn the key like in a car.

Not tech exactly but has trains ever done an article about grafitti? Not just the hoows and why's of its legality but of the how's and why's it is done at all?

You might be surprised...

It depends on the brand.

If you put that kind of information in 'public'.  Some 'foamers' might try to apply it, with disasterous consequence.

Fortunately - there are a number of steps that have to be undertaken before you get to the Minute 42 seconds that are on the video.

Make sure you check your fluids and clean the carbon traps:

A article on the various fuel strategies the Class 1 carriers are using to minimize one of their largest budget items.  Strategies concerning fuel purchase.  Strategies concerning fuel delivery to locomotives.  The 'back office' support necessary to implement these strategies.

Resistors may be silent (not completely; there is inaudible very very low level noise as they expand when heating and contract when cooling), but the fans that cool them and keep them from melting or expanding and twisting out-of-shape, sure do make a whine.
