Signals for piggy-back trains

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.
