Bachmann EM-1 Question
« on: September 25, 2013, 08:53:28 AM »

I'm a little confused re the variations on these models. Bachmann lists the four road numbers thusly -

#7600 - single headlight / large dome
#7604 - large dome
#7614 - large dome
#7627 - dual headlight / small dome

First off, which dome are they talking about?

Secondly, I assume #7604 and 7614 are the same as #7600 (single headlight / large dome)?

Thanks,
-Mark

I guess I'm not clear on the single/dual headlight thing either. They both look the same to me -

Mark,
I have 7614 and 7627.  :?
I am still not clear about the double headlight on 7627, and also cannot distinguish any difference in dome size.
Will opt for Skipgear to enlighten us.

I could be wrong but I think they are referring to the headlight itself, being single or dual beam, think NKP Berkshires.

Ah, I see the dome "legs" now. Thanks!

As for the dual headlight, I actually have #7627. However, the dualness is escaping me. Am I missing something?

The headlight is really bright - something that caught my attention right away. I wonder if that's what differentiates it from the others?

If you look at the single light vs. the dual headlight versions, they have masked the lens on the dual headlight version to represent the twin sealed beam headlight installed later in the life of the loco. Most of the photos I can find of dual headlights are after the locos were renumbered to the 650-679 series.
The domes is as mentioned earlier...

The fist 20 produced, numbers  7600-7619, were built in 1944 with the sanding apparatus shrouded on the front sand dome (Large dome).
The second 10, built in 1945, numbers 7620-7629, were built with the front sand dome the same as the rear sand dome (Small dome).

While looking for a photo of 7627 with a dual headlight, I found an interesting photo of it pulling a mail express train in 1945 up the Cheat River Grade. It's only 3 months old at the time and still has the single headlight.

I believe the chose the 7627 for the dual headlight because there is not a lot of photographic evidence to prove them right or wrong. The dual beam headlight was a later retrofit that came only on a few locos, about the time of the renumbering. I have found 657 (7607) and 670 (7620) with dual headlights after their renumbering but beyond that, photos are scarce.

So, model-wise, the only difference between the single and dual headlight versions is the lens?

Thanks,

 The railroad replaced the large single element light with an insert that held two sealed beam bulbs late in their life. The housing and other details are exactly the same.

Strictly speculating, maybe they mounted a small LED directly inside the headlight housing instead using a "light pipe" and an LED mounted under the headlight).  That would make it brighter.

Don't know where one would find a closeup of an EM-1 dual headlight, but it's the same basic principle as these F-unit headlights.  Two sealed beams in one round housing:

 ;) Yes, looks as if EM-1 received two lights in later version.

Very good shot showing the dual sealed beam headlights in an EM-1. The model has a silver mask printed over the lense of the light with two smaller clear circles to represent this. I really don't know any other way they could in such a tight place. I am working on a P7-D that also had dual sealed beam headlight and I was thinking of two pieces of fiberoptic glued into the the normal lens housing to recreate it. There really isn't room for that in the EM-1.

Oh duh, it's pretty obvious when you look at it with the headlight off  :P



Thanks for help, guys.

Cheers,

Have not looked at it from that angle, was too eager to see I run.
