[quote]QUOTE: Originally posted by cacole I think what they mean is that because the QSI equipped locomotives require a higher than normal throttle setting before the motor starts to turn over, you cannot MU the Broadway Limited with non-QSI equipped locomotives. As long as you are running MUs of Broadway Limited there should be no problem, but I wouldn't try to MU a Broadway Limited with an Athearn Challenger, even though both have sound, because Athearn doesn't use the QSI sound system and it probably has a different start voltage. [/quote] The new BLI PRR K 4 will not MU on DC with other BLI engines because of the engine inertia option. It automatically starts slow even with the DC on full and can be controlled to some degree, but it will not MU with anything on the planet except maybe another BLI K4. It is sort of like the DC momemtum that some Power packs use.
