The temptation is definitely there, especially when I see shots like these- 10 Century series vs 3 EMD's, wow! and yes I've gotten real close to CR'ing a black GP-38, though candidly that green and yellow Precision scheme is much higher on the "list" as I saw those all over back in the 70's
You must be telepathic though, this last weekend I put away my PC meat products train and unpacked my "Can Opener" transfer. I don't have much of a yard to store equipment in so I roll the era forward (or back) so to speak, likewise the Long Branch commuter train will get upgraded to an NJT Comet set .

This freight though is an equal opportunity offender; if the Conrail doesn't get them (and trust me I have plenty of friends who hate it like the devil) then it's the tagged cars or the eot "FRED" in place of a caboose.

Two Atlas "Trainman" factory units that I've made some minor mods to the paint and modified the motor harness to series. They're smooth, unexpectedly powerful and will flat out crawl almost imperceptibly, though I'd like the U23B better in black and would love another matching GP15.

Really nice models and I feel fortunate I snagged them when they were still available and relatively inexpensive.

Some modern prototype freight cars are hard to find so I've used some Lionel's and K-Lines to supplement the usual Atlas and Weaver offerings, the coil steel gon is a K-Line that I two-railed and drilled and tapped Kadees to.

This 2-Bay DT&SL CH was an LCCA car and still not too hard to find on Ebay these days, albeit you have do the same steps as on the K-Lines to 2-raIL, and it's a devil to disassemble thanks to Lionel's "kid-proofing."

I generally keep the more pricey PRC freight cars for a short while so I don't typically fiddle with them as in weathering or tagging hence my Weaver 50's in particular are the primary victims of that treatment, with some exceptions.

The FRED is a AAA battery powered flasher and adds a lot to the freight train's appearance IMO, especially at shows where it's just around and around for hours.

I had a hell of time tying to catch it lit with my camera, so I'm posting both times I did.

I'll post a few shots of that NJT commuter here later once I pull the NY&LB train off.
