Siding length isn't an issue if the line is double-tracked the whole way.

If there are any problems, lack of a siding somewhere nearby leaves the main line blocked. Also, at the destination, you need some place to put the thing, except for bulk mine trains which go round and round a loop.

On a double-tracked line, lack of a siding somewhere nearby leaves one of the two main lines blocked. That's still serious, but less than what you are saying.
