Production of P30CH from U30CG (2000-2001)

A long time ago, I wanted an N-scale General Electric P30CH diesel locomotive, and this is a story about a railroad model that I modified based on another model.The model car is overseasMinitrixA diesel locomotive called GE U30CG.

The original product has front and rear handrails, but it was a used product that was missing, so it looks like this (lol)


The U30CG is a GE diesel locomotive made for the ATSF (Santa Fe Railway), and is a full cowl version of the GE U30C with a steam generator installed.The G at the end of the model number stands for Steam (G)enerator.The sides of the body were corrugated to match the streamlined passenger cars, and the bonnet had a rounded style.

Compare with P30CH

The overall length of the U30CG is 67 feet 3”, while the P30CH is 72 feet 4”.It's about 5 feet shorter, but I think it's probably the closest in terms of shape.I read it in middle schoolRailroad Model CraftsmanI still remember the article in the August 1984 issue of the magazine “Modeling Amtrak: Part II, Available Models” that said “Somewhat resembles P30CH”. Minitrix, the manufacturer that makes the U30CG, also has Amtrak paint in its lineup.

Modified parts of U30CG

  • Bonnet modification

    Bonnet modificationThe P30CH's distinctive feature is its angular bonnet. The U30CG has a rounded bonnet, so we have to modify this part.The technique was a heaping pile of putty and filing that anyone could think of (lol), and I started carving it out while looking at photos of the actual car.The area around the cab window also needed to be sloped a little, so putty was also applied around the cab.

  • side modification

    side modificationThe side of U30CG is corrugated.The impression would be quite different if left as is, so I modified the sides.I wasn't confident enough to prepare the sides with putty and sanding, so I covered the corrugated edges with a thin plastic band.It's a secret that the plastic vane was too thin, so the areas where it reacted chemically with the adhesive became bumpy.

I feel like there are a lot of things that are different, such as the radius of the roof, the length of the vehicle, the location of the radiator, etc., but I thought it would be ok as long as it created a good atmosphere, so I passed on everything (lol)

P30CH style U30CG (lol)

P30CH from 2001

I was able to get a square front, so I guess it's okay.I was planning to buy and install detail improvement parts around the lights and skirt, but I couldn't make any progress.In the end, it was completed as is (lol) I'm sorry for the random finish as usual.
