@Andy Hummell posted:The sound cars are certainly fun. We often run trains with 4-5 of them in a consist. A few times we ran some long freights with 16 sound cars mixed in... you should have heard those trains!
WOW! I've had five in a 40 car consist, it was pretty noisy, sixteen of them in any sized train would be something!

Another time we had a train pulled by 23 Beeps.
My VL-BB was part of a four BB quad-headed train at the NJ-HR at one of the Trainstock visits, only issue was with smoke it kept tripping the track breaker! Now, the 23 BEEPS would have been a fun train to see! 
I have half a dozen BEEPs, I'm creating a couple of multiple-unit command consists using one command board. I'll have a triple PRR one and a double Reading one.
