I want to motorize my Santa Fe Super Chief. Its original instruction mentions 5300 but it's marked obsolete on BS.com and now re-released as 10153.
In the same time 88002 costs few times less, e.g. $15 on Lego.com vs $55 on eBay.
So does it make sense to acquire more expensive 10153, or can just go for 88002? Are they compatible? What is the difference?
Update: Is the key difference in the way how does engine receive electricity? From metal tracks or inner engine (like Red Cargo train does)?
