Notes S-4:

4) S-9 Electrical

Is this a model that utilizes power from the rails? Yes No For what:

If this model utilizes power through the rails, complete the table below:

Power Source	Supported	Vmin	Vmax	Vmax Tested
AC	Yes	No	N/A	12	OK
DC	Yes	No	N/A	12	OK
DCC	Yes	No	Vmin & Vmax tested by decoder test team.

If a decoder is used to control the devices in the model, the decoder should be checked separately for conformance by the DCC decoder test team. Find the decoder brand and model, check the list of Conformance Warrants issued. If the decoder used has been issued a Conformance Warrant proceed to step 4A below. If not, contact the Manager C&I Department for more information on having the decoder tested by one of our volunteers specializing in testing decoders for conformance.

Notes S-9 S-9.1: S-9.2

4A) DCC Decoder Test

Test	Procedure	Expected Result	Pass or Fail
DCC Test	Make note of the decoder used (Manufacturer and Model) Search NMRA.ORG for a Conformance Warrant issued for the decoder. Note the Conformance Warrant # Turn on the DCC system and acquire the decoder by address.	From a throttle the tester should be able to acquire control of the decoder and complete the test below.	Choose an item.
The decoder should be able to independently control FL(f), FL(r) and F1-Fn. If it exist, turn on FL(f) (also known as F0(f) or forward headlight).	If it exist, the desired forward headlight as specified by the manufacturer should illuminate.	Choose an item.
Instruct the decoder to move backward and turn on FL(r) if it exist (also known as F0(r) )	If it exist, the desired rear headlight as specified by the manufacturer should illuminate.	Choose an item.
If F1 exist, turn on F1	The extra function, if it exist, should turn on.	Choose an item.
Continue to test F2-Fn for as many output functions as there are.	The extra function(s), if it (they) exist, should turn on.
If the decoder is equipped to produce sounds such as whistle or bell press the keys for these functions.	The extra functions, if they exists, should turn on.	Choose an item.
If the decoder produces sounds associated with motion, increase the throttle to ¼-1/2 of full.	If equipped for sound, there should be sounds for motion such as wheel sounds or other as specified by the manufacturer.	Choose an item.
Analog Decoder Test	Make sure the analog mode is enabled in CV29, bit 2 =1. Place the car with decoder installed on an analog powered (DC) track with positive voltage on the right hand rail.	If equipped for sound the car should make sounds associated with motion and the headlight in the direction of travel (if it exist) should be lit when FL is pressed.	Choose an item.

The RPs below do not impact the awarding of an NMRA Warrant. However, please take the measurements and report.

5) RP-7 Clearance

RP-7 Clearances provides guidance on clearances for cars and locomotives. The silhouette of a clearance gauge actually checks for clearances of structures, bridges, tunnels and platforms based on AAR data. The RP-2 Clearance Gauge, whether incorporated into the NMRA Standards Gauge (Type I) or a separate stand-alone Clearance Gauge; it is suitable for use to check most rolling stock. For modern cars such as double-stacks and tri-level auto carriers use the plastic modern clearance gauge attached to the Type I gauge. RP-7 Clearances are intended for tangent (straight) track and/or very broad curves.

Will model pass unobstructed through the area specified by the RP-2 Clearance Gauge for this scale? Yes No

Identify gauge and version used for this check:

6) RP-20.1 Car Weight

RP-20.1 provides for a recommended car weight for various length models in each of the major scales between N and O. However, the RP does not define a recommended weight for every scale. Further information on the advantages of the recommended weight can be found in the text of Recommended Practice. Weights should be taken to +/- 0.1 oz.

Refer to the current version of RP-20.1 at NMRA.ORG for the target weight of this model for its scale and gage. Measurements for this model	Pass: Yes No

Length of this model	Inches
Target Weight	ounces
Weight of this model	ounces

Notes RP-20.1:

7) RP-23 Bolsters

RP-23 provides recommended specifications for bolsters (both body and trucks) that are designated to permit easy interchange of trucks between cars. Recommendations are not provided for every scale. Passenger car bolster bearing heights should be used on tenders and high speed freight cars generally fitted in the prototype with passenger type trucks. Further information on bolsters and the specific recommendations can be found in the text of the Recommended Practice.

Compare your measurements to current applicable RP-23 at NMRA.ORG Measurements for this model in decimal inch:

Truck center bolster bearing above top of rail (Bc)	Pass Fail
Kingpin size (P)	Pass Fail
Truck bolster hole (E)	Pass Fail

Notes RP-23:

8) RP-24.1 Journals and RP-24.3 Axles

Compare your measurements to current applicable RP-24.1 at NMRA.ORG RP-24.1 and RP-24.3 focus on Journals and Axles. Please record the following data about this model:

Type of Journals:	Type I Type II

Type of Axles:	Type I Type II

9) RP-25 Wheel Contour

RP-25 provides for a recommended wheel contour for optimum track holding ability and most prototypical appearance within the interchange limits of Standard S-4.

Does this manufacturer claim on their packaging and/or documentation or other published materials that this model’s wheels have RP-25 Wheel Contours? Yes No

History

September 6, 2018. Changed S-4 Wheel Width Dimensions table, Wheel Width column from “(W)” to “(N)”. D.A. Voss

October 29, 2018. Changed S-7 Clearances paragraph to RP-7. Therefore, clearances no longer required for NMRA Warrant.

October 30, 2018. Changed paragraph 3, Wheel Dimension table to include the measurement of Flange width for S-4.2 (Standard) wheels.

March 24, 2020. Changed paragraph 5 to reflect the correct references RP-2 (Track Gauge) and RP-7 Clearance reference. Added requirement to list version of gauge used.

August 7, 2022, removed table of wheel dimensions and referred Inspectors to compare measured values to current applicable S-4 published on NMRA.ORG Requires all dimensional measurements to be taken to within +/- 0.001” Added drop down pick list to replace multiple check boxes. Other error corrections and formatting. By JM Juett

November 16, 2022, modified Section S-2 to be consistent with Loco Inspection Form. Removed question about coupler color, as there is no Standard on this. Made formatting changes in page 1, sections 1, 2, and 4 to be consistent with loco inspection form. Reduced the requirement of double entry on data and information from S-4 N, D and T for RP-25. By JM Juett

February 22, 2023 Formatting changes and error corrections. By JM Juett

November 26, 2023, added field for link to product on manufacturer’s website. Added more spaces to Fax number and email address fields. Modified drop down list for more clarity. Moved positions of Flange Depth (D) and Width (T) to mirror the tables in S-4.x. By JM Juett
