As I recall, the VI-1 set pulls about the same load as a 12 diesel, pulling 3 cars of each, at 40% bonus on the cars. (Of course, you also get the extra bonus points.) By this time you are probably using 15+ diesel engines and have cars that give 300% bonus. As you point out, the Maglev is limited to 4 types of cargo and you are limited to the set of one-each.

The first Maglev trains are useful for completing Contracts for Lucy (and above), working towards completing the Goldtrans Record Breaker.
