| NOTE: The following categories are the opinion of N Scale Supply and are very subjective. These are provided to give you a rough idea of the quality of the product. Your mileage may vary. | 
| Performance: | Very smooth speed range, top speed seems very realistic. According to ER Models the top speed is approximately 90 mph. | 
| Sound/Noise level: | Somewhat louder than Atlas or Kato engines, but not obnoxious. Fairly constant volume through speed range. Noise probably caused by gearing used for realistic speed curve. | 
| Overall Value: | Especially considering that this is the first entry into the N Scale engine market, ER Models has made an impressive showing. At retail of $139.95 for two powered engines, this is an exceptional value. Printing quality and performance is very good. The wire handrails are outstanding. |
