Main Track is different than yard track if everything is equal. The yard can absorb more abuse account low speeds and long periods without loading/unloading cycles. (think track modulus and smaller impact effects)...what gets beat up in yards are switches & frogs which, by nature, are the weakest link in the track structure. (ask da snowman about what happens to the leads in his yard)...

If you had decent joint maintenance in the past, UP will get as much life out of that rail as possible. If the joint batter suddenly gets bad, you will see CWR right quick and in a hurry.

The joints are in bad shape five miles either side of MP 40. Half the rail head is worn away in most places and nearly down to the web in a many others. Bolts are loose and several joints are marked with spray paint markings (by whom, I don't know). The coil springs on those cars sure get a workout when the trains pass through Baldwin.
So, where's the CWR? Or is UP simply waiting for a RoadRailer derailment?

Was this train in a siding, or a secondary track??
Most main tracks on Class 1 RR's have all CWR.

hello all. I was watching a train roll through the crossing on the west end of Altoona today and was enjoying the "clank-clank clank-clank!" sound the wheels made on the rail joints. but it got me thinking. why has my area not been given CWR? while i prefer the jointed rail, it was something that i was pondering.
that as well as why CWR is more ideal than jointed rail. i had heard from someone that jointed rail was needed to slightly expand out for wider-spaced wheels etc. how does CWR handle that situation?
thank you for any help in advance
