"train machine" Deck 2015

Playing

It's his Deck in Train + Fortress, which isn't particularly rare. Recently, I felt that "dueling is all about ATK", so I made it.
Basically 《Revolving Switchyard》+ Express → Battrain Special Summon → Dora Xyz is the main force. However, if you have Cyber or Slime, don't use 《Revolving Switchyard》and aim for battles damage.
When the train doesn't go around, I endure it at Fortress. Fortress itself has no resistance, but you can revive it with a single Train or Cyber, so I think you can interrupt your opponent's combo. I'm also grateful that he can send Battrain to GY, which (should) be useful when equipped with a gear frame.
Skidre is strong after all. Along with 《Revolving Switchyard》, trains and Cyber go wild. Of course, Dora's effect is also negate, but Batrain and Derrick's GY effects are not hindered, so don't worry about it and send him to GY.

Strength

Since Lv.10 is adopted besides the train, it is easy to put out Dora. Care in the event of an accident while in Fortress. Warriors under Skidre.

Weakness

There is no countermeasure against the GY effect (Graydle or Nightmare). Without 《Revolving Switchyard》, it is difficult to rebuild. Defenseless when summoned.
You can't beat a Deck that easily beats Dora!

Customize

I'd like to try something like Gustav x 2 = 4000 damage with soul charge... but I'm worried because I'm mostly using Dora as an extra. Is it possible to aim for 8/10 synchro with Veiler?
