Whats Odd with this Train Set?

Plarail trains traditionally have an engine and two wagons. Here, they wanted to include a second piece of rolling stock, so the tender was left out in favour of it. BTW, what is that second wagon? A car transporter?

But was there really a "tradition" in place when these vintage sets were released or is this just what you think the reason is?

The trains are traditionally 3 pieces and at this point in time I believe there was no actual mold for a tender so one wasn't included.

Still seems strange that they would make a mold for the steam engine but not what was supposed to go with it. Wonder why they just didn't use a tank engine which would of made more sense, anyway, water under the bridge...

The first Plarail trains didn't yet focus on railway logic, despite the introduction of real life engines and trains at the time.

Another, Old release that has strangely not included the required tender for the engine. Wonder why? http://www.jauce.com/auction/t490315457

is the last car used for carring trains?
