For some reason it appears that most DCC modellers always choose the no.1 end of a double ended locomotive to be the "default forwards" when using DCC - is there a good reason for this, apart from the defaults for DCC ready or factory fitted DCC loco's ?

Personally, about half of my diesel & electric fleet "default forwards" from the no.2 end (which also has the crew), although these are mostly loco's that have been "hard wired". Law of averages dictate that a fair numbers of the prototype are driving from the no.2 end at any time.

Maybe, it's easier to see which way the loco is actually going to go before you move away - not a problem for those whose locos have lights.

Just wondering.

It's a good idea to choose a standard and the stick to it, especially if you have a lots of locos and/or guest operators.

In my case all my locos are steam, so it's easy to decide which end is the front. Despite that, at least one "DCC Ready" loco went the wrong way, after initial installation of a decoder using the installed socket. Obviously the DCC socket had been wired up the wrong way.

I only had to change a setting in CV29 and it worked correctly. That's one of the advantanges of DCC. You don't have to re-solder the connections if you, or the manufacturer, make a mistake

I have been thinking about this for a few days and have come to the conclusion that, having studied numerous photos of diesels and electrics, that it is common practice to run either way round. I have even found photos of class 33's running double headed with the number 1 ends together.

On my fleet I have altered my 33's so that I have varied the leading ends. My Warships, on the other hand, appear to be symmetrical so it doesn't matter which way round they operate.

Finally, don't forget that diesels and electrics are designed to be driven from either end, that's why all the turntables were removed in the 60's.
