Signals for piggy-back trains

• Entry corridor
• Stop for piggy-back trains
• Piggy-back obstruction board
• Piggy-back route board
• Examples

The Lötschberg and the Simplon line have been reconstructed recently to enable the operation of piggy-back trains. To keep costs low on most of the double track line only one track was reconstructed. A piggy-back train must not drive on a wrong track. To prevent this a train route setting system is provided which prevents the pigs from entering a forbidden track automatically. The signals shown here are an additional safety measure.

Entry corridor

	Start signal (entry corridor) (Anfangssignal)
	End signal (entry corridor) (Endsignal)

Within the entry corridor marked by the boards shown above the engine driver of a SIM train has to confirm via radio that he is driving a SIM train.

(The abbreviation SIM means: Simplon-Inter-Modal.)

Stop for piggy-back trains

	Caution (for piggy-back trains) (Warnung)
	Stop (for piggy-back trains) (Halt)

Piggy-back obstruction board

	Piggy-back obstruction board (Huckepack-Verbottafel) These boards are located near the ground (similar to dwarf signals). The sharp edge shows to the belonging track.

Piggy-back route board

			Piggy-back route board (Huckepack-Wegtafel) The thick lines show the allowed tracks, the thin lines and the violett dot show the forbidden tracks for piggy-back trains.

Examples

In the examples below all tracks closed to piggy-back trains are marked in violett.

Example 1

Exit onto the left track. Stop for piggy-back trains.

Example 2

Exit onto the right track. Line clear for all trains.

Example 3

Exit onto the left track with auxiliary signal. A piggy-back train has to stop before the first turnout.
