Room #315 climbs from GLOVE to TRAIN. Of their 5 letters, 5 differ (positions 1, 2, 3, 4, 5); each of those needs a rung of its own, so the shortest imaginable ladder has 5 rungs — par here is 7.
So 2 rungs are sidesteps: somewhere a correct letter gets spoiled for a moment, or a letter from neither word is borrowed.
Five-letter words have few neighbours, so plan the last rungs first: which words could sit just below the target?
Five-letter words and ladders of six to nine steps.

Hint: the first step
