The word Troas (G5174) is used 6 times in the New Testament, 4 times in Acts (twice in Acts 16, twice in Acts 20), once in 2 Cor 2:12, once in 2 Tim 4:13).
Acts 16 is the account of the Second Missionary Journey.
2 Cor 2 could be the outward portion of the Third Journey after the riot in Ephesus (Act 19) and Paul went to Macedonia (Act 20:1), and upon the return leg of the same journey, by that time, we read that there was a congregation in Troas. Paul together with the team stayed in the city with the church (Acts 20:6-12).
It took them 5 days to sail from Philippi to Troas (Act 20:6).
In 2 Timothy, Paul's last epistle, Paul was in Rome, writing to Timothy who was in Ephesus. And Paul asked Timothy to come to visit him and to "bring the cloak that I left behind in Troas with Carpus, and the scrolls, especially the parchments" (2 Tim 4:13).
Again, it shows that Troas was at the crossroads from Asia to the west.

特罗亚这个名字（G5174）在新约圣经中使用了6 次，在使徒行传中使用了4 次（使徒行传16 章两次，使徒行传20 章两次），哥林多后书2 :12 一次，提摩太后书4:13 一次）。
使徒行传第 16 章记述了第二次宣教旅程。
林后2章可能是在以弗所骚乱之后（徒19），保罗前往马其顿（徒20:1）。之后第三次旅程的回程部分，那时我们读到在特罗亚已经有一个教会聚会点。保罗和他的团队一起留在城里的教会（徒20:6-12）。
他们花了五天时间从腓立比航行到特罗亚（徒 20:6）。
在保罗的最后一封书信《提摩太后书》中，保罗在罗马写信给以弗所的提摩太。保罗请提摩太来看他，"我在特罗亚留于加布的那件外衣，你来的时候可以带来，那些书也要带来，更要紧的是那些皮卷。"（提后4:13）。
这再次表明特罗亚处于从亚西亚到西方的十字路上。
