Page 18 Track section module MX9
The drawing below once again shows one of many possible ways to connect a MX9 to the layout.
This time only one MX9 is shown that is connected to blocks with an uneven number of track sec-
tions. Blocks with just two track sections may be mixed with blocks containing several sections. A
block with three track sections may be connected to two main sections (double sockets). It doesn’t
matter whether an F section is paired with an L section, or an L with an H section. As already men-
tioned, connecting three sections of one block to two double sockets require that one connection re-
mains unused.
Length of low speed sections:
Low speed sections are usually used to slow down a train ahead of a stop section. A low speed sec-
tion is set to low speed only, if the train is expected to stop in the following section.
All slow down sections of a layout have to be of identical in length and are typically about twice as
long as the stop section, about 3 - 5 feet (1 - 1.5m) for HO.
EXAMPLE –
Blocks in a continuous loop
The number of trains that can operate in a closed loop with block control is always one less than the
number of blocks available. 7 trains can safely operate on such a layout with only one MX9, 15 with
two MX9 etc. That is, with 8 blocks made up of one F and one H section. Fewer trains, if blocks con-
tain more than two sections.

EXAMPLE –
Bidirectional block control
In a bidirectional line like this, the travel direction determines the block sequence. For this reason
only one connection of the double socket can generally be used.

EXAMPLE –
Unidirectional stations (i.e. staging yards)
In unidirectional stations, each platform track is usually split into two sections, whereby the second
section is the stop section. Both of those sections are connected to one double socket of a main sec-
tion at the MX9 module. Of course, all tracks can be used in both directions when driving in manual
mode (e.g. shunting work).
The sections before the stop section are commonly used for slow station entries and would have a
low speed limit applied to, such as L or U.
A main section is used for each track section containing turnouts at each end of the station. The
other sub section of those main sections must not be used. The line before and after the station is
usually part of a block as described in the previous examples.

EXAMPLE –
Bidirectional station
In order to have stop sections in the right places and of suitable length, a platform track in a bidirec-
tional station needs to be separated into at least 3 sections.
If two or more lines enter or exit a station, as shown at the right end in this example, special consid-
eration is to be paid to the section configuration in the turnout area. Because a section cannot be
used in two different routes at the same time, track sections that can be used for parallel entry or exit
