Prototype Railroading
Run around brake hose
Interesting video: run around brake hose; I didn't knew that - would be interesting to model:
Undaunted by field repairs
Apparently railroads can do some high echelon field repairs if needed. I was familiar with the rip track concept and the idea of setting out cars or locomotives for later retrieval or repair, but I never really thought about the level of work that might be attempted away from a proper facility.
I had occasion to pass by this UP facility near Chickasha, OK today. Actually I made the occasion, as it is a little out of the way but I usually go on purpose if in the area to see what may be up on the UP.
hunting oscillation
The other day I posted about freight cars both real and model that have a slight lean to them while sitting or moving on a level track. During a brief scout of photos and videos, looking for examples, I saw this instead:

Traveling Tom's video shows a couple of gondolas with some unusual action to the trucks called hunting oscillation. I wasn't familiar with the term and I don't think I've personally witnessed a real life occurrence.
interesting loco
i saw a interesting road unit ( 6 axle) close to fresno yesterday.
sorry no photos, was driving. unit type? no rd number seen. i only had about 30 seconds of view.
but was yellow ( not up yellow) had progressive ( i believe was the word on the side) and the wording about cat power.
any know about thus unit?
Norfolk Southern and Progress Rail unveil GP34ECO
The GP34ECO is powered by a 3000 hp 12-710 EMD engine that is EPA Tier 4 compliant using SCR exhaust aftertreatment. The locomotive is intended for yard service and intermediate operations.
NS built the locomotive core at its Juniata Locomotive Shop in Altoona, Pa. and worked with Caterpillar and Progress Rail on final assembly, engine, and aftertreatment system work. The locomotive ecieved a new crashworthy cab and new cab electronics.
Dissimilar Consists
Is it common for the real thing to consist normally aspirated diesels with turbocharged diesels?
I expect that these days the issue does not come up much. Maybe with smaller railroads with a mix of power or in yard work for the majors, but I am working on speed matching my locomotives and tried some turbo/non-turbo combos. It made me wonder if this was easy for the prototype or if special arrangements or settings had to be made with the engines given the possible horsepower spread.
Did the prototype mark clearance points?
Did the prototype railroads back in the 20's mark clearance points on sidings or spurs?
Caterpillar and Chevron collaborate on hydrogen for EMD 710 engine
Caterpillar and Chevron collaborate to check if hydrogen is a viable replacement for traditional fuels for line-haul locomotives and marine vessels.
They have chosen the EMD 710 which is still used as E23 on marine vessels. For that use it is EPA Tier 4 certified with exhaust aftertreatment.

Has anybody noticed that the coal trains are being replaced by tank trains?
I walk in a park bordered by the BNSF main line into Kansas City and there is a noticeable decline in coal trains but an increase in tank trains. Also noticed that there is a covered hopper as the first and last car in a tank train, what are they for? Also have seen a lot of equipment in very used condition heading west, some of it so old the graffiti has faded away to unreadable. Just yesterday there was a BNSF unit that the paint had faded back to the Santa Fe colors.
