I noticed that the hand rail on the end platforms is continuous and runs across the steps. Is this the way the real locomotives are built or is this an oversite by the manufacturer? In the pictures I have looked at I cannot tell how it should be.
David, I have never actually seen a real NYC T-3a, but after reading your question googled images of the NYC T-3a Electric Motor and found several good photos of what appear to be T motors . It seems that on the prototype the railing immediately above the steps leading to the platform was open to allow passage. It would be a simple fix to make if you wanted to modify the model, but before I would do that I would want to do some further research just to make sure. I would also write to Scott Mann at 3rd Rail to get his take on the issue as I would think they would have based their model off of detailed prototype drawings. There is always the possibility that the railing above the steps seen in prototype photos where actually modified after delivery from the manufacture ALCO-GE. That is my take, but perhaps there are others more knowledgeable than I about the T-3a who can give a more definitive answer to your question. Bo
