Which of the following is true of Trans Continental Railways?

Both 1 and 2

The correct answer is Option 3: Both 1 and 2

Trans-Continental Railways are major railway lines that:

• ✅ Run across a continent, connecting its two opposite ends — this fulfills Option 1.

• ✅ Were often constructed for both economic and political reasons, such as enabling trade, integrating remote areas, strengthening national unity, and facilitating military movement — this supports Option 2.

NCAERT: "Trans–continental railways run across the continent and link its two ends. They were constructed for economic and political reasons to facilitate long runs in different directions. Trans–Siberian Railway, Trans–Canadian Railway, The Union and Pacific Railways are some of the examples."
