BQ23-7 Build Thread

[u18b]

I can't answer about pool power- although i would have my doubts.

As for time period, 1990-92, i know the windows were still used.  But by about 1993 or 4, they converted them to B units. So if you model mid 90s then all B units.

I model all the way back to 1986 so i need both.

This thread makes me truly wonder what a CQ36-7 would've been like...

[u18b]

Ed, there is no reason why we couldn't have fun and make one.

I fact, I plan to make a BQ18-7 or 8!

Hi, just skipping through this topic and I noticed that someone was polishing up their model with toothpaste, for what it is worth, and purely as side comment not trying to change the topic, another fine abrasive you can use is water and cigarette ash mixed into a paste. This mix does not have the flavors found in toothpaste (usually essential oils) that can sometimes effect the resins. The down side is the smell but it is not residual. Cheers.

As far as I know GE had offered their full model line at that time with the option of a Q cab. So it is not that far from fantasy.

The concept of the Q-cabs was a good one... what likely kept the concept from being used further (likewise on the extended cabs of a few Frisco GP50s) was new crew agreements that reduced the number of crew members on a train... the first steps to what we have so commonly today.

Frisco didn't have GP50s with Q cabs, it was BN, and from the BN order, not the Frisco order.  The Frisco units were phase I units, BN 3100-3109, while the BN ordered ones were phase II, BN 3110-3162, the last 5, 3158-3162 were the Q cab units.

The Q cab was a GE designation.
I'm not sure it is an appropriate moniker for the EMD GP50s BN had.

Just like a Q cab is not a "north American" cab either.

Finally got Shapeways page to cooperate long enough to order my cabs (got version 2 if yourinterested). Since these cabs were offered across the whole dash 7 lineup I plan to try one on a C30-7.If it requires to much rework I will just do a pair of 23-7s.The big decision will be CSX or GVR.

It hopefully would only require some work on the bottom of the cab, if you need that doing it should not be a big job to alter one specifically for you.

Look forward to seeing your work.

I don't believe there was a special designation for the extra length cabs on the GP50s.  BN didn't class those units differently than the other GP50s.

Is there a particular Atlas Blomberg truck frame that I need to be looking for?.. or are all the 4-axle frames interchangeable within the Atlas line of products?

You want plain old Blomberg trucks from a GP38 early or GP40.

You do NOT want trucks from a DASH-2 as they usually have the "snubbers" on one axle- which is a little shock absorber.

I used Atlas part number 480305 this is Common to GP-7, 9, 30, 35, 38, 40 and 40-2, simple job of un-clipping the existing frame and clipping the new one on.

Perfect, thanks!
