Hello all,

The track supplement sets 7850 (straight, containing parts #3228 and #4166)
and 7851 (curved, containing parts #3229, #3230 and #4166) where marketed as
4.5 V track. You could upgrade the 4.5 V track to 12 V by adding 12 V Track
Insert parts, which you had to buy as separate packages.
The points and crossing were not upgradable, there where individual 4.5 V and
12 V versions of these track elements.
The LEGO(R)-LDdraw-Lgeo Parts Reference at
http://titan.informatik.uni-bonn.de/~uhlmann/partlst.html
also identifies #3228, #3229 and #3230 as Train Track 4.5 V

I'm against naming the track 1st generation, 2nd generation and so forth. Such
names don't describe the characteristic differences. Besides that, it also
ignores the close resemblance between the "Blue/Tapered" track
and "Grey/Slotted" track, and the big difference between them and 9 V track.
So I like to keep these two versions in the main group "Train Track 4.5 V",
with the subdivisions "Tapered" for the old blue track and "Slotted" for the
newer grey track.

Rounded ends ? I didn't recognise roudend ends at the parts of the oldest type.
It´s more like "Tapered", and that´s my suggestion for the descriptor in this
case.

I think we should keep calling all parts "Track", for else they will not sort
sequentially together. And things like "straight" should come last for the
same reason, to make the different types sort together. Also, I believe that
the 4.5 V, 12 V and 9 V designations that you left out are very useful.

Lets leave "Bottom" out. "4.5V Slotted" gives enough information.
I would say "Train Track 4.5V Slotted Straight"
> 12v parts
> center conductor straight
> center conductor rounded
Hmm, I would like to call these parts:
Train Track 12 V Power Insert Curved
Train Track 12 V Power Insert Straight
So, besides the names for Train Track 4.5 V parts I wrote out in my last mail,
Train Track 4.5V Tapered Crossing
Train Track 4.5V Tapered Points Left
Train Track 4.5V Tapered Points Right
Train Track 4.5V Tapered Curved Inside
Train Track 4.5V Tapered Curved Outside
Train Track 4.5V Tapered Straight
Train Track 4.5V Slotted Crossing
Train Track 4.5V Slotted Points Left
Train Track 4.5V Slotted Points Right
Train Track 4.5V Slotted Curved Inside
Train Track 4.5V Slotted Curved Outside
Train Track 4.5V Slotted Straight
we would get:
Train Track 12 V Crossing
Train Track 12 V Decoupler Base
Train Track 12 V Points Left
Train Track 12 V Points Right
Train Track 12 V Power Insert Curved
Train Track 12 V Power Insert Decoupler
Train Track 12 V Power Insert Signal
Train Track 12 V Power Insert Straight
Train Track 12 V Signal Base
and
Train Track 9 V Crossing
Train Track 9 V Curved
Train Track 9 V Straight
Train Track 9 V Points Left
Train Track 9 V Points Right

Yesterday I've noticed something interestingly about the track supplement sets
7850 and 7851. Printed on the boxes are drawings and photos showing grey track
that is both tapered and slotted ! I've never seen that particular variant in
real life.
Chris Dee, was this the missing link you where referring to ? Does someone
have them ? Or was it just an internal prototype and did they forget to make
new pictures? Stranger still, you'll find the mysterious images even on the
most recent boxes of 4.5 V track, although in my experience always track of
the "Slotted Only" type emerged from the box. (Believe me, I've checked)
Greetings, Manfred Moolhuysen.

| Snipped most of a well thought out posting. (...) I agree with your ordering, and tapered is a better descriptor than rounded. Where I differ is in the use of 4.5 V, 12 V and 9 V in the naming. While I don't think gen 1, 2 or 3 are good, these (...) (25 years ago, 11-Oct-99, to lugnet.cad.dev)
