Tab-On-Car System

In 1964 John Allen adopted the “tab-on-car” system to achieve a realistic

ebb and flow and random distribution of rolling stock. With the addition of

a few simple rules an operating session could be picked up where the

previous session left off and continue for as long or as short a period of

time as desired.

The tab-on-car system was a

four-step cycle of car movement

dictated by a color-coded tab

carried on top of the car. Each

side of the tab had a large color

block indicating the first

destination to which the car was

to travel, and a small color

block indicating the second.

On the Gorre & Daphetid RR

colors on the tab could

indicated a destination or a

group of destinations. For

example, white indicated one

destination, Great Divide, while

green indicated points along the route of the Gorre Peddler; Sowbelly,

Squawbottom and Cross Junction.

If the color code indicated multiple destinations, lettering on the colored

block clarified to which destination the car was to travel. Once the car had

traveled to the two destinations shown on one side, the tab was turned

over to reveal two new destinations. Upon completing the trip to these

destinations the tab was once again turned over and the cycle repeated.

In the example shown, the car travels from Great Divide (white) to Port

(blue, F = Anabel Ferry) then Andrews (orange, A = Andrews as opposed to

Corsa, also on the Andrews Peddler route), then Gorre (yellow, G = Gorre as

opposed to Dapheid, connected to the Gorre Peddler route by a branch

line), then back to Great Divide and the cycle is repeated.

On the Gorre & Daphetid RR the rules were simple:

A car once spotted at a location had to remain there for 12 scale hours

(1 hour real time).

At the start of an operating session, this time limit did not apply and

all cars were ready for forwarding (with no "set-up" required).
