As a result I want to run freight motors, and the North Shore had a few unique freight motors, which make nice signature locomotives for my layout. However, the North Shore freight train crews also had the habit of running with both poles up; done I understand to reduce the strain on the overhead when drawing large amounts of power when starting heavy freight trains. They also had the habit of swinging both poles to hang over the same end of their four GE freight motors #452, 453, 454 & 457.
This causes a problem when trying to replicate this on the models. So the first picture show a CNS&M Steeple Cab Imported by MTS Imports, Inc. I've replace the MTS poles with Eatman Custom Engineering poles I got off eBay. These are effectively a modern version of the Suydam poles, with better wheels/sliders.
As you can see when down there is plenty of room between the two poles when down.
The second picture show a CNS&M Steeple Cab Imported by The Car Works with MTS poles showing that they too can be run with twin poles collecting current.
However, when down these poles foul each other as can be seen here. Not so good.
They also foul each other when both up facing in opposite directions. An unlikely situation, but I show it just the same.
Here is an over head view showing the biggest problem of all, which is that one can't stow both the the poles down on one end, a typical North Shore Line practice by the train crews of the freight locomotives.
The poles I have to hand are as follows from left to right; a Suydam original, an Eatman Custom Engineering pole, a Car Works pole, two MTS poles (one modified to two springs), and finally a PSC pole that I have modified by shortening it and replacing the pole with a scale thickness guitar wire.
Order reversed for the top view.
Both of the modified poles to the left of the picture are still too wide to do the whole both poles pulled down on one end thing that the North Shore Line freight train crews did. The rather lovely Car Works poll suffers from being too long, which prevents the prototypical functioning I require, and for those of an inclination to such matters, still scales at about twice the length of the prototype..
Plan at this point is to go back and rebuild the PSC kit again. I've already cut it in half to shorten it, but I reckon I can take another couple of millimetres off its length, and more importantly I plan to narrow the width of the end. Hopefully, this will allow two poles to be pulled down on one end.
Oh yes. Made my replacement pole too long, forgot I was working in 3.5mm to the foot, not 4mm. Oops.
