The IDF located railroads inside the smuggling tunnels along the Philadelphia axis - which testify to the smuggling industry that was run through those tunnels.
The railroads were used to drag a kind of wagon-carriage along their length, with which a huge amount of munitions were smuggled into the strip.
Officials in the IDF said that the work of destroying the tunnels along the axis has not yet been completed, and that there are tunnels in which exploration and scanning continues.
In addition, there are areas on the Philadelphia axis where the drilling has not yet been completed - and therefore the IDF's assessment: there are still smuggling tunnels along the axis that we have not yet located.
