The G's had these problems:

Frame Cracks
Cancer products in the electrical equipment.
Finding parts.

Is most of the old PRR part of the NEC still 25 cycle?  New electrics can change stuff like that on the fly!

That is what I am referring to about the GG-1! The oils or the transformer inside the cab is now considered hazardous material.

Electricity today is on the 60 Hertz standard. To modify down to 25 Hertz is expensive for the ampere draw that the GG-1 had. As far as I know of nobody uses 25 Hertz anymore, some countries still use 50 Hertz.
To convert from 60 to 25 Hertz is a very expensive process, it would be cheaper to produce 25 Hertz electricity.

I think what 'aky13' is asking is what color and stripe version is the GG-1 # 4935 supposed to be?
The Pennsy used about five differant striped versions of the GG-1 in differant colors.

The GG-1 was phased out because of electrical requirements, they were 25 Hertz or cycles, also they used some type of electrical transformer or other electrical equipment that is now considered unsafe to use. Current electricity is 60 Hertz.
Although I would love to see a GG-1 run again, it is almost financially impossible for the real life one.

If you want to see a real GG-1 go to the Pennsylvania Railroad Museum in Strasburg PA.

Golden State I think. I'll have to grab an old Williams catalog. Nice looking cars and my only passenger cars - so far.

Just before K-Line got devoured by Lionel they had a set of Golden State passenger cars and a diesel engine to match.
I don't remember Williams ever having a set of Golden State passenger cars, but I could be wrong. Only been around Williams for about 7 or 8 years.

How about making GP-30's in roadnames for the northeast railroads?
Reading Lines had a small fleet of GP-30's in the 1960's.

  Yes, k-line made 072 curves in 027 height. They also made 054,042,031,and 027.

The only problem with buying K-Line track in those sizes is that you must buy it used or on a clearance shelf at your local hobby shop. Lionel quit making K-Line track with unusual sizes to cut production costs.

Lee F.

Not sure if there is 027 track in 072 radius.
Gargraves makes track sizes up to 120 inch radius and that will work with 027 track with just adapter pins installed. Hope that helps you.

Lee F.

When you have parallel tracks, especially at the corners, you have to make sure that the engines don't hit each other when going thru or passing at the curves. Sometimes as much as five & a quarter inches are needed between curves(measured center rail to center rail) even when using 031 & 042 curves. Another thing is to start the inner curve about five inches before the outside curve section of track.
I have three Williams SD-45's and I run them on 031 & 042 curves, have not tried them on 027 curves. Also have a set of Williams F-7's that I run on 031 curves. My GP-9's will run on 027 track with no problems, other than Lionel 027 switches as the housing sticks up too much.

This is my personal opion about track, I use Gargraves as their switches are very low to the ground and allow almost anything to pass thru, no clearance issues. I have had major league trouble with Lionel's O gauge switches made since 1995.

GTBob,

Are you using this engine near another set of parallel tracks?
If so you will need to measure the overhang of all engines at their widest point on the outside of the rails to see how far to space your tracks. Also how much overhang does any of your other engines need?

I have a Reading T-1 steam locomotive that has an extremely large rear cab overhang and will hit other engines and cars on the parallel track going around a curve that most of my other engines don't have any problem with. Unfortionately I built my layout before purchasing my T-1 locomotive.

Using algebra,

Po = Pn   Original power same as new power.

Po = Vo x Vo/Ro   power is V squared over R

Vn = 2 x Vo  New voltage is twice original

Pn = 2Vo x 2Vo/Rn = Po = Vo x Vo/Ro  substitute

4 x Vo x Vo/Rn = Vo x Vo/Ro  combine twos

4/Rn = 1/Ro   divide out (cancel) Vo squared from both sides

1 x Rn = 4 x Ro  Cross multiply

Rn = 4 x Ro  Drop 1 x (redundant)

So, same electrical power, @ twice the voltage and half the current, the resistance is quadrupled.  (X 4)

Hope this helps. 

Sincerely,

Joe Satnik

Joe,

I am totally lost when it comes to algebra! I may know some geometry but that is about it, mainly basic math. Also I think that you are trying to describe an electronic circuit and how it works rather than a basic electric circuit.

Basically when you increase resistance in a circuit you increase the power consumed. So the point that I was trying to get across is that a lower volt light bulb should let you have more power to the motor, this will be noticed with a lower watt transformer.

Lee F.

Joe,

I think that you are mistaken on the 24 volt bulbs drawing half the power.
A 24 volt bulb will actually draw more power(watts) because the resistance is higher.

Lee F.

Most of the Williams passenger cars unless over 16 inches each in length should be able to run on 031 curves with no problems.
If they have operating couplers and weigh just over 1.5 pounds they should handle 031 curves very well, some passsenger cars may work with 027 as well.
Most of the newer passenger cars have little if any problems. It was the older(15 to 20 year old) passenger cars made by Williams(before Bachmann) that had problems.

Hi JP,

Thanks for the tip on ordering one of these streetcars. However you forgot to mention that they come with STICKER SHOCK!!!!  $229.95 for a single streetcar is what I call sticker shock! I can buy a new diesel engine for the same price and use it to pull a train on my layout, but the streetcars don't have couplers on them.

Lee F.

Another thing about using 24 volt bulbs is that it may slow down your engine's top speed, as it uses more power to light up.
An 18 volt bulb should be the highest volt bulb to use with any O gauge train.

J O, the prices for light bulbs could be old stock left over from Williams. That's a very good price, but who needs 50 light bulbs?

Lee F.

Hi JP,

Thank you! I know it may seem dumb to some people but Bachmann never said how to order one of these.

I work for a contractor that works for the state of Florida, and if you don't mention exactly what you want done by somebody 'Look Out!' The results will not be anywhere near what you want!

Lee F.

Where do you go to order this streetcar?
It isn't listed under traditional O gauge.
