I remember LTEX 1441 and photographed it in shortline service, paired with a similar painted one maybe 10 years ago. The crew those days said it was still too much power for the work they did. Eventually replaced with a pair of SW1504’s instead a short time after. Never saw the GP15-1’s again.
Hoping Athearn will eventually do the yellow schemed GP15 lettered for Appalachicola Northern again. They have the blue ones coming at least.

LTEX 1416 is in the same scheme as 1427. 1427 before repainting. 1420 had a different Conrail logo. Thanks for posting the pics. I got to see 1427 a lot and have pics when it was running on Conrail Shared Assets from the split date to the mid 2000’s when NS retired them all. That replacement P3 horn occurred after 2003 I believe but it still had the Leslie RS3L sound. I miss seeing them run and they had a unique throttle sound that’s for sure. |

The DRGW caboose is nice. Might get one just because 😏

Lol they were known on Conrail as wheel slip specials! That’s crazy that they were looked at as too much power. |

I like the concept of the diner conversion cabooses. More sales out of the moldings with just acouple of cheap plastic extras.

You gotta think though, they were only moving a dozen or so carloads at a time about 20 miles each way, switching one or two at a time with a pair of those things. They did not last long out there before getting the SW’s. |

That's funny because the SW1504s had the same HP and actually make more tractive effort than a GP15-1.

so after doing a quick Google because I wasn't familiar with them.... the SW1504 was basically just the MP15 before there actually was the MP15?

Hmmm. Better wheelslip control on the SW?

GP15-1: Weight: 246,000 lb Tractive Effort: 47,000 lbf SW1504: 248,000 lb Tractive Effort: 62,000 lbf And, looking a little further afield: M51: Weight: 120,000 lb Tractive Effort: 179,500 lbf Horsepower: 980 For when you REALLY want to move something heavy: tanks-encyclopedia.com/coldwar-us-heavy-recovery-vehicle-m51/I had just seen a video on this vehicle, as I research my intended loads for the Rapido Magor flat. I've got the M103's--maybe someday I can build an M51 to join them. Ed |

Hmmm. Better wheelslip control on the SW? 31% more tractive effort, which you can think of as a measure of "grip". "For an electric locomotive or a diesel-electric locomotive, starting tractive effort can be calculated from the amount of weight on the driving wheels (which may be less than the total locomotive weight in some cases), combined stall torque of the traction motors, the gear ratio between the traction motors and axles, and driving wheel diameter." |

A one-ton difference in weight isn't going to affect t.e. that much!
Might your figures show continuous t.e. for the GP15 and starting t.e. for the SW1504?
SW1504 starting t.e. is 62000, continuous 46800.
GP15-1 starting t.e. is 61000, continuous 48000.
Numbers from The Diesel Shop.

Here is a shot of the new Roundhouse F7:  Looks to be a good model/super detail fodder at the price point. The general contours look close to the Highliner shell. |

Appreciate the photo of the new F7. IMO something looks "off" about the nose and windshields.

Are they using the original frame and fuel tank with the mounting tabs?

That Roundhouse F7 looks like it would be a good club runner. It certainly looks more appealing than the detailed FT shown on the Rapido News 190 thread.

I saw Athearn is doing the D&RGW scheme but the road numbers they chose were from a later phase.
