The 10 minute delay was probably put in place for a couple reasons.. A to stop abuse with the "teleport" effect .. and B to create a cash flow path Via the ID/IR voucher.
Here is another possible way to Curb the abuse of this system: only allow trains to be moved from the museum to the Players HOME city.
Phase 2 of this solution is to Limit how often a players home city can be changed to once per 24 hour period. (same as association switching limits).
Play the Game instead of Gaming the system.
