In some fields of higher matheimatics the definition that any number divided by itself equals one is "superior" to the rule that any number divided by zero is undefined. So the correct answer to zero divided by zero equals one. That's one definition used in some higher mathematical fields. But usually it's just considered indeterminate. So there is no real answer - it depends on what you're doing. As a software writer, one thing I know for sure is that ANY quotient logic that attempts to perform a division by zero, will cause the application to crash![:D]

This made me lose it. I replied "Well, I don't really have the time to build kits, not to mention locomotive kits are usually somewhat challenging, and the RTR is way better looking than I could ever make it look". They were infuriated by this and yelled "How are you ever going to know if you don't do it yourself!?" After that they made a quick leave. What's the big deal with RTR locomotives and rolling stock? They offer a quick way to get your trains running and look great. I would consider Kato locomotives RTR, too, even if you do have to apply the detail parts. Most people including myself just don't have the time, the skills or the patience to build kits. And mind you I'm just talking locomotives (kit rolling stock is fun, but RTR is nice once in a while). So lay off, pro-kit builders. Anyone else feel the same way as me?[V][?] I'm a smart, gifted and talented individual, and can build, assemble or repair just about anything you put in front of me - or at least I'll try. However, I don't put other people down because they can't. It took many years of trial and error for me to learn what I know and develop my skills. We're not all put together exactly alike. I also buy RTR any time I can. Tracklayer I bet when asked you also help those that can't build, assemble or repair things. I"m sure they learn a bunch too. [:)]

I think I learned this in abstract algebra, or perhaps it was in Partial Differential Equations.
QUOTE: Originally posted by vsmith I have to say this is one encounter you would never have in large scale... I can only say that in my scale G, I only wish we HAD more kits of locomotives! 95% of everything motive related is RTR which leaves alot up to our kitbashing skills. what kits there are, are pricey and often poor running. Selection is still very limited. I've had better luck scratchbuilding and bashing to get what I want than waiting for kits that might not ever get produced. So as it is RTR is just a given for most modelers. As for RTR in HO, I personally feel you should do what ever helps YOU to enjoy the hobby, these guys were being just plain rude!

QUOTE: Originally posted by davekelly Who is more a "model railroader" - the guy that builds only Bowser type locomotive kits and uses RTR track, shake the box rolling stock and structures, or the guy who uses RTR locomotives and rolling stock but handlays every inch of track, scratchbuilds every building and concentrates on realistic operations? Along the same lines - it seems that another popular pasttime is to call anything less expensive than what one runs "junk" and anything more expensive than what one runs as "things for those that have more money than brains." As far as I am concerned, and this is just my opinion of course, if a person is running something that looks like a train and is smaller than 1:1 scale, and is having fun doing it - that person is a model railroader.
