Killer Trainline

Here's a Tren-Sudoku mashup nobody asked for. :P I think it turned out pretty fun. Enjoy!

Normal Sudoku Rules Apply

Between line rules Digits found on the line must be strictly between the digits found in the attached circles. These between lines circles are also "circle clues" for the Tren rules, below.

Tren rules (slightly modified from standard rules, do read) Locate some blocks in the grid, each of which are either 1x2 or 1x3, which may not overlap each other. Each clue must be used by a block and each block may contain at most one circle, and one small corner mark, but could contain neither. The value of a digit in a circle represents how many different locations to which its block can be moved by sliding it in the direction of its short end without overlapping another block or going out of the grid. If a block does not contain a circle, it must still contain a valid digit to be used as its "circle clue." Staying stationary does not count as one of these locations.

Killer Cage rules Small corner marked values in the grid are killer cage clues. All of these clues must be located in a block in the final solution. Digits in a block must sum to the killer cage clue, if given in the block.
