Rick - is it possible that the default setting somehow got changed to require double digit numbers ? From the Manual:
Building a Route
Building a Route allows you to control a group of Switches and Sub-Routes with one
command. In the CTC options menu (see page 48), you can set the rate at which the Switches
and Sub-Routes in the Route will throw.
There are three key differences between LEGACY and TMCC Routes:
1. LEGACY Routes can contain other Routes. These are called Sub-Routes.
2. LEGACY Routes can throw Switches at a user adjustable rate.
3. LEGACY Routes, while they are single digit ID# Routes by default, can be changed to be
double digit ID# Routes if you wish. It is possible to choose any number 1-9 and have
all Routes that start with that number become double digit Routes. You can have both
double digit Routes and single digit Routes. In the CTC options Menu (see page 48), you
can select Routes 1-9 to be double digit Routes, making a total amount of 99 Routes.
While double digit Routes make more Routes available, they are slower to throw, requiring
2 button presses. Single digit Routes allow for quick throw of Routes with one button
press. An example of this implemented on your layout would be mainline single digit
Route ID#'s 1-8, and 9 double digit ID# Routes in your yard that all begin with ID# 9,
i.e. 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99.
