HP E-7

HP E-7

Postby areibel » Mon Nov 23, 2009 10:04 pm

HP had two versions of their E-7 diesel. The original is on the bottom, the shell is stamped metal and the sideframes are, uh, unique? The top one is the later version, it has a cast nose piece with a stamped body, and it had the lost wax side frame castings. It also has some small added roof panels made of stamped metal

Here are some additional photos of the HP Products E-7 A unit, as well as the E-7 B unit, which were often referred to as "Diesel A" and "Diesel B" in HP Products advertisements.

Both units are 6 axle units. The power truck, which is on the rear of each unit, uses the same configuration as the real life E-7: A1A, meaning 3 axle, the outer are powered, with a center idler axle to help distribute the weight of the unit. The front trucks are all idlers, with the outer axles actively used for electrical pick-up and the center one passively.

A close up of the power units, with the A1A power trucks:

Both my E-7A and E-7B came with New York Central decals. Both are somewhat curled, and as such would not take good photos. I will try to scan them later on and post them.

About the Prototype: The E-7 was the 8th model of the 6 axle "E-Unit" series of passenger locomotive. The engine was of the A1A-A1A configuration, meaning two trucks of 3 axles each with the outer trucks powered and the center ones not.

The last three of the series, the E-7, E-8, and E-9 are close in body design, with the biggest difference between the E-7 and the E-8/9 being the grilles on the sides of the cab and the design of the porthole windows, with the E7 having square windows and the E-8/9 having circular windows along the flank of the engine.

There is only one E-7 A unit left, and it resides in Strasburg, PA at the Railroad Museum of Pennsylvania; PRR# 5901.

428 A-units were built between 1945 and 1949. 82 B-units were built between 1945 and 1948, none remain today.

In keeping with the "prototypes/models" theme of this section, I felt it prudent to post some photos of real E-7 locomotives.

Wow, Rob, your locomotive is brilliant!

I've seen some HP E7 on Ebay, but didn't buy it, because I was sure it is too rough... maybe I was wrong?

Thanks, the cast side frames helps a lot in the looks department. But, they are not real good runners.

Gorgeous paint job! :thumbup: :thumbup: I just wish there were some "drop-in" power trucks available to turn such a set as your E-7's in "good runners." I know that I have a few "hanger queens" around in my collection of TT stuff.

Rob,

Probably two reasons they aren't such good runners are limited pickup and poor wiper design, plus they are only powered to two wheels (one truck). Using a motor with archaic magnets doesn't help either...

Never mind that, they look really good!

Thanks again guys!

I probably should have mentioned that the photos I posted yesterday are of models I no longer have. I do still have these though :) (and others I need to dig out)
