Gentlemen,

I didn’t have any intention to touch off such a powder keg. I also got the impression from that past post the Mr. Stan Ames and Bachmann are somewhat synonymous. That being said, I would be interested to know, if the speed restriction Mr. Ames alluded to above was known before production of the K-27, why did he gear the engine that high? I might have been more inclined to go in the 20:1 range making both ends of the spectrum better.

I am a modeler and consumer of Large Scale Products and can not or do not speak for any manufacturer. From time to time I try to help out a variety of manufacturers on a number of projects. Some ideas are incorporated in the end product while others are not. I do happen to like the Bachmann K27 and it is my favorite locomotive on my railroad. For my Birthday I purchased a 4th and yes I operate on 2-4% grades over long runs.

I tried to answer your initial question of the prototype speed of a K27 with factual information and am sorry it evoked the responses it did.

As to why Bachmann chose the gear ratio it chose you will have to ask them. I hapen to agree with your analysis that a 18:1 to 20:1 would likely have been a better choice. A number of different modelers have reached the same conclusion.

In my opinion it would be beneficial for the large scale community to discuss and come to a conclusion on what the desired speed should be for a model. For example if we could agree that the top prototype speed of a model locomotive should be achieved at say 20 volts DC then those that like fast running could still achieve it by doing to 24 volts and those that like prototype speeds could achieve it at lower voltage.

As you have seen though it is very hard to have such discussions as it quickly turns emotional.

So why then is your name on the Mallet instruction manual with a credit as being (I believe) a consultant?

Fr. Fred,

I fear you have the right of it, and respectfully request that everyone please let the personal feelings that seem to be controlling the situation here go by the wayside.

Stan,
Thanks you for your response, and I applologize for the misconception that there was an employment tie between yourself and Bachmann. I have seen the video you reference, and feel it is a good show of the K’s abilities. The only question I have about the video, ‘Is that straight DC track power or are there electronics above what is provided by Bachmann involved in the slow start?’. Your answer and Kevin Strong’s have been the only ones that directly addressed the question asked in the first place “What was the prototype top speed of the K-27?”.

“In my opinion it would be beneficial for the large scale community…” is an opinion I share, however there are far too many in this hobby that feel like several members of the club I belong to, and I quote them “We don’t need no stinkin’ standards!”. Until everyone respects that each of us has our own opinion these disputes will continue.

Tony,
A consultancy on a given project does not necessarily mean that the consultant has final say. When I started this thread I was soliciting the consultancy of members of this thread to provide information regarding a particular piece of data I did not possess. Information has been provided by several members and it is MY final decision what I wish to do with that information. The fact that Stan’s name appears on the instruction manual as a ‘consultant’ only gives he credit for his input into that manual. His input may have been only one small contribution, or it could have been the entire manual - this we will never know.

Thank you all for your input, I have received more than I had bargained for. As for the Hatfields and McCoys, please leave it out of this forum, I will not choose sides, thereby reducing my enjoyment of this hobby. I solicited information, not a war.

But...but...but... we haven't had a good war here since Bob shut down "Off Topic! :P :lol: :D

Zoobs-
Because some folks are simply LSOS.
They wouldn’t know the “truth” if it hit them in the face.

“Proof”?

Well over 200 separate files of it.

Some day it might be useful.

For those who do not believe, this is just the tip of the iceberg, so to speak.

I am not going to “prove” anything, rather I shall allow others to do so.

While there may or may not be things I “know”, from past experience with one or two utter and complete lying morons trying to copy selected portions of posts and forward them along to Philly, I won’t publish, have no intention of doing so.

Like I said, I will let others do so.

Have fun!

Steve,

Maybe that is why Bob did what he did.

TOC thanks you.
You have saved me time and time again from costly misstakes. You have also sold me one of my best running locos I have. the funny thing is the two best Locos I have both have BBT drives in them.

Anyway, the link you have here the guy that started it I know. Rob wonted to bring his K-27 to my place and run it but my tunnels are just a little to nerow for it. after reading that link I am happy about my tunnels. I would have hated for it to have problems at my place. I’m sorry he is having truble him and his brother are both really great kids and have some really nice stuff.

There was some discussion of the K27’s speed in the Gazette a few years back… wish I could remember which issue. Anyway, the basic gist of it was that the K may have been capable of speeds over 30mph, but not a lot over. And due to track conditions its speed was kept much lower.
