Well, I think if we are talking about defending railroading then railroading must have a non-pejorative use. I think that would be play where the GM decides what happens next, and what flows from the players' action declarations for their PCs, pretty much independently of what those actions are. The players' contribution, in this sort of play, will typically be providing characterisation.We cannot even agree on a narrow meaning for railroading. Some people want it to mean only when the players object and other to apply it to any DM Force situation, and others to any instance of a linear plot even where the player are aboard the train.
This will probably require GM Force, as least in the sense of manipulating the fiction "behind the scenes" so as to maintain the sequence of events. As I've posted upthread (I think), techniques here include providing extra "breadcrumbs" or hooks" if the players miss the first lot; replacing dead villains with new villains to keep the evil plot moving along; having NPCs react in pre-determined ways regardless of the details of PC-NPC interaction; etc.
I get the impression that this way of playing RPGs is fairly common. If there's a group of players who don't like it, then it would seem pathological for them to nevertheless play a game like that!
Maybe. Maybe not. I think it would depend on the extent to which the set-up is (extended) framing and the extent to which the climax and decision matters. This is not said flippantly - an extended reply follows. I can't give an example of the contrast I'm drawing using Gumshoe scenarios. But I will try and describe two Prince Valiant scenarios that mark the distinction I'm drawing, both found in the Episode Book.So, then a question. What about mysteries, in which whodunnit is known to the GM. Rather than breadcrumbs, you have clues. Is this a railroad?
Before you answer that - we can consider Ashen Stars, a Gumshoe-based game, in which the standard concept is the PCs are a team of freelance troubleshooters, hired to find out what's really going on and deal with the situation. The GM is encourage to have "deal with it" include some important ethical or strategic choices. The GM knows whodunnit. The GM does NOT know how the PCs are going to deal with it.

The Crimson Bull, by Jerry Grayson, unfolds over multiple events in place as the PCs lead the bull of the title to the Vale of Mud. But these are really just extended framing - they don't presuppose particular prior decisions by the players other than to lead the bull to the Vale; and they provide colour and enrich the situation concerning the bull. The actual moment of crunch is in the finale, when the players (as their PCs) have to decide what to do with the bull and the pagan sacrifice of it by the wise woman of the Vale. I think it's a really well-conceived scenario.
A Prodigal Son - in Chains, by Mark Rein-Hagen, has some interesting elements but, as presented, is a railroad in the sense I've tried to set out above. The tell-tale in the writing is stuff like this:
At this point the Adventurers’ actions can have a direct impact on the story. They can meet with the yeomen leaders of the peasant army, try to sneak into the castle, run to get help from nearby nobles, or attack or harass the peasant army. Bryce does what they ask, but strongly requests that they let him speak with the peasant army.
Whatever happened, you need to have things end up with Bryce’s father, the duke, dead. . . .
Just as things seem to be winding down (one way or another) Bryce steps out of the crowd . . .
At this point you need to have things wind up with someone trying to kill someone else as a result of the heated argument over what to do. It can be a peasant trying to kill a yeoman, Alia trying to kill Samson, Samson trying to kill an Adventurer; but no matter what happens, Bryce throws himself in the way . . .

In other words, there are moments of choice that are thematically weighty (how do the PCs deal with the politics and associated dynamics between the "prodigal son", his father the duke and his sister Alia) which have to come out a certain way for the scenario to play out as presented. When I used the scenario I picked up some of the key story elements but just ignored all of Rein-Hagen's sequencing and railroading.
I've gone into this level of detail because I think we have to look very closely at the details of how situations and events are being presented, how they relate to thematic framing and resolution, etc, before we can start to identify whether or not we're looking at a railroad.
Also, I think what Jerry Grayson has done is not only better as RPG design (at least relative to my preferences) but displays more ingenuity as a RPG writer. I think it takes a lot of cleverness to set out an extended framing that builds up the pressure in the overarching situation but without forcing resolutions on the way through that then force railroading if the whole scenario is to be used. I can think of a few other published scenarios that pull this off - at least some of Robin Laws's in the Hero Wars Narrator's Book; and as a site-based version, some of those in a 3E-era d20 supplement called Wonders Out of Time (I can't remember the publisher).
Published adventures that set out mazes for exploration don't involve railroading (eg ToH, WPM). And published scenarios that are really just story elements don't have to be railroading either - I'm thinking of two Classic Traveller scenarios I've used, Annic Nova and Shadows. What I have had to do with those is add to them to turn them from bare descriptions of (respectively) a starship and an installation into thematically salient elements of our game.Most published adventures have to engage in some amount of railroading by their nature (at least most mainstream adventures).
If the published scenario is meant to be a "story" scenario, then I agree that these overwhelmingly are railroads, but they don't have to be as per what I've posted just above.
