Railway artillery appears not to have been pursued as a Philippine workaround

Did the United States consider Philippine railway artillery as a way around restrictions on fortifications?

It apparently did not, despite the concept's possible utility; American policy was also moving toward withdrawal from the Philippines before the war.

The United States does not appear to have pursued railway artillery as a way around restrictions on Philippine fortification. Building tracks as infrastructure was a suggested workaround, and the idea is judged worth considering. One possible reason for its absence is the contemporary movement toward an American withdrawal from the Philippines. That explanation remains tentative.
