I loved taking tours of old railways
when I was in grade school.
كنتُ أحبّ التجوّل في أنفاق السّكك
القديمة عندما كنتُ في الابتدائيّة
In der Grundschule bin ich gerne
an alten Bahngleisen entlang gelaufen.
Quand j’étais en primaire,
Quando ero alle elementari,
mi piaceva esplorare i vecchi binari abbandonati.
Eu adorava andar nos trilhos antigos 
quando eu estava no primário.
Когда я учился в начальной школе, любил
бродить по старым железным дорогам.
