Features and Changes Included in the Quantum Upgrade Chip Features Common to Analog and DCC Downloadable Sounds and Software - Allows future sounds and code improvements to be installed in locomotive without removing the memory chip. (Requires additional download module to be connected between your PC and program track; to be announced). Back EMF Load Compensated Speed Control -  This is an extremely valuable new feature. BEMF is a method of monitoring motor load and compensating for load increase automatically. It improves running and slow speed operation. Locomotives with BEMF decoders are much less likely to stall at very slow speeds. Improved Sound Profiling - Allows individual sounds to remain audible even at low system volume settings. Added Individual Sound Volume Settings - This includes 1) Horn, 2) Bell, 3) Motor, 4) Fan, 5) Turbo, 6) Air Brakes, 7)  Air Pumps, 8) Air Let-off, 9) Short Air Let-off, 10) Squealing Brake/Flange, 11) Dynamic Brakes, and 12) Coupler Sounds. Sound of Power™ - Added to simulate increased power demands under acceleration and decreased power under deceleration. Synchronized Steam Dynamo Sound with Headlight Turn On Operation. Progressive Shutdown Capability - includes states of Disconnect, Standby and Total Shut Down. Available for DCC and DC (with QARC Technology and Quantum Engineer) Extended Shut Down Scenario Extended Start Up Scenario. Functional Air Brakes - Slows train with added brake squeal and air-line let off sounds. Playable Horn or Whistle

Features in NMRA Digital Command Control (DCC) Regulated Throttle Control included for the first time in Quantum DCC. Rapid Engine direction Change - Direction can now be changed rapidly allowing more reliable uncoupling operation over track magnets. Previous Quantum operation would gradually slow locomotive to a stop before changing direction often missing the uncoupler magnet. Added CV’s CV 5 V-High. CV 51 Mute Volume - Sets mute level. CV 55.110.5 Ditch Light Strobe Hold Time. CV 56.0 Packet Time Out Shutdown. CV 56.12 Chuff Interval Scale Factor allows adjustment of chuff rate. CV 62 On/off control of verbal announcements. New CV’s Added to Program Motor PID Parameters. New Sounds New GE pump New E8 dual horn New Sound Sets in Steam in Diesel

Features in Analog Regulated Throttle Control with Real Inertia Effects. There have been many improvements in Regulated Throttle Control since its introduction. Separate sound records for Horn hoots and Whistle Hoots. Load Settings Allowing up to 15 Levels of Inertial. Special Heavy Load Option - Allows near constant momentum of trains up and down grades. In Heavy Load, the throttle will increase or decrease motor revs and Sound-of-Power™ without noticeably changing the locomotives momentum which allows operator to individually control locomotive motor RPM and sound settings during operation. QARC only. Selection of Helper Type Locomotives including Normal, Lead, Mid, End and Pusher type helpers. Direction Setting for Improved Lighting Control of Locomotives in Consists. New accurate way to set V-Start. Improvement in Changing Direction in Neutral - Provide three hoots when moving in reverse and two hoots when moving to forward. QARC™ Technology Added. Upgrades your Quantum locomotive to be compatible with the Quantum Engineer thus allowing many features only accessible in DCC to be accessed in analog. If your QSI locomotive did not support the Quantum engineer, the Q2 upgrade will add this feature.
