Re-rail

A re-rail attempt is the direct opposite of a derail attempt, in the individual tries to resume the original topic of discussion in a thread, debate or discussion that derails as a result of a red herring debate or thread hijack.

Usage
Re-railing a thread, debate or discussion has varying amounts of sucess depending on the individuals involved and how cooperative they are. If a large number are emotionally invested in debating an irrelevant point, a thread re-rail can be difficult to accompish.

Individuals may try:
 * Asking people to stay on topic.
 * Reminding people what the topic is originally about.
 * Asking debate moderators or similar to deal with those derailing the topic.
 * Ignoring the irrelevant topics and presenting relevant resources, such as article links.

These can however have limited effectiveness, especially if two individuals have become emotionally invested in 'winning' what is otherwise a trivial debate.
