Conventional Block Wiring & Phasing Two Or More Transformers?

I think the question is a matter of what happens when an engine with multiple pickup rollers is crossing into another block. If one roller is in one block and the other pickup roller is in the next block, and they are both linked together, how does this work? How do the transformers deal with it as momentarily they are electrically linked? They wouldn't be if only 1 pickup roller were used but nearly everything out there has 2.

Sorry--this post dealt with HO DC operation, which apparently is not what the topic is about, and has been edited/removed.

To find out how to wire more than one transformer to a multiple loop layout where all loops connect I have purchased Greenburg’s Model Railroading with Lionel Trains volumes I & II, The Lionel Fastrack Book, and Lionel Fastrack Model Railroads book.

 

They talk about how to make sure you have both / all transformers in the same phase and explain how to do that. 

 

They explain to break the loops into control / power blocks which I understand.  What I don’t understand is when an engine is going from one block, powered by transformer 1 to another block powered by transformer 2.

 

The way I see it is, when the engine moves across from block 1 to block 2 it will stall unless transformer 2 is already powered up, which means both transformers would  be connected when the wheels of the engine cross the two blocks.

 

Am I wrong ?  And wouldn’t that create a problem between the two transformers?  And what about there being a voltage difference?  I would think it might burn up something inside the transformer if not inside the engine.

 

I know there are a lot of folks here that have been around before the new Command Control systems came along and have used multiple cabs in the same scenario I am using.  I would greatly appreciate some information on how to operate between two power / control blocks with two or more transformers.

 

Thanks,
